Hi all!
Been thinking of upgrading my 1915cc to a 2175cc this winter. I want to have the same combo as Darrel Boomgaars engine.
DPR 78.4 x 94, FK-8 and Wedgeports with IDA's.
Just curious about the wedgeports, how good are they? Do they need to be checked by a local machineshop? Valve job? Springs checked?
Also does anyone have a link to a topic of Mark Herbert where he describes how to port the manifolds for wedgeports / tips/tricks.
Thanks!
Jesse

they will work "out of the box" and I have used them that way before.
However, If you are buying them to go fast, then don't sell yourself short. I strongly recommend that you do a few things to get the maxx out of them.
1. have someone, (or yourself) remove all the ridges left from the port and chamber mill work. These ridges can impede flow dramatically.
2. have someone lay in a nice 3 angle valve job. After you have done the ridge removal chore.
3. I'd just go ahead and install those VW-650 valve springs. You may have to add shims to get the install height right. They will keep valve float away (and seat destruction).
4. cut the tops of the guides back far enought to allow for max lift plus .050" w/o hitting the retianers.
These are all good things to make your heads last a good long time, and it will get the max performance out of them.
Getting them setup properly will prevent any sort of "dropped valve" failure that will destroy the whole motor.

Thanks Tom for your reply.
I'm deciding between Wedgeports and Steve Tims Stage 2. Which head will make more power? (Wedgeports with the mods of above). I would like to have around 180hp.
Thanks,
Jesse

I have a set of the CB Wedge Ports on my street car, it is a 2332cc, 10.1 compression on pump gas, it has a FK-8 cam, and everything on this engine is off the shelf. The engine was taken to Heads Up Performance and put on the dyno, it made 190 hp through the 1 ¾ header and through the Magnaflow muffler. This engine has been beat to death by my wife and I on a regular basis and has been together for five years with no problems!

Go witht he Tims stage 2's you will not be disapointed. Call and talk to steve nice guy and can tell you what you need to get 180 hp.
I have stage 1heads from him and 160 hp was easy.

I have the 46x38s and it could use a little cleaning above the seats and the valves are longer and hit the valve covers wen I use the 1.4 CB high lifts so with stock length valves and 650 springs would be a good choice. But I say that those heads has very nice ports and is super for the money and wen set up it can blow the competition.

Nothing against Steve’s heads, but if you can get an off the shelf head that will make an easy 190hp, isn’t that better then 180hp? My engine made 160hp at 5500 and pulls like a tractor. |

It has been so log ago I don't remember, sorry. I'm leaning towards the 44 X37.5 but I could be wrong. All I know is they work real well! |

Dom,
Mine made 160 @5500 as well.
Stage 1 heads with 40X35.5 valve and Kadrons.
I have not had it back on the dyno with the webers.

I'm having a real hard time believing that... It must have been on a real loose dyno... |

Why do you have a hard time with that?
160hp is quite doable with Kadrons. A.J. has done it, the bergs have done it and Joel Mohr has done it.

The wedge ports are great heads right out of the box. They don't need a three angle valve job. They come with that already. They don't need a "fluff and buff" or anything. The ports flow really good just the way they are. The only thing that would be recommended would be to check max lift on the set you have and make sure that you won't run into coil bind issues with the cam and rockers you have. Don't just use the stats. You really need to measure this stuff out because a lot of rocker/cam combos lift the valve a lot further than what the specs say they will. If you want better springs, simply order them with better springs.
The heads are capable of producing impressive power as long as the rest of the combo is up to it.

Thanks for all the replies!
Mike, maybe you can tell me how much is would cost to get them to 54cc so I can get 10:1 CR.
Thanks!

I don't have a problem with that, I just don't believe it, I know what it takes to make that kind of power, nothing against AJ or Joel, but I'm not sure where you got your dyno figures from but I can tell you that most of the dyno's lets just say in Orange County show hi, I have seen engines that were done at other dyno's and the read about 30hp higher then say like Heads Up, so if you saying your engine made 160hp on Rogers it would be more like 130hp, now that I would believe, I have seen it plenty of times. |

I don't have a price sheet for CB, but it's just a phone call away to ask, and all you really need to do is order 'em that way. |

Also check that there are no spark plug threads bare in the chamber.
Some may need an extra plug washer.

Here is the machine shop rates for CB: http://cbperformance.com/services.aspI would do what Mike L suggested-get good springs like the CB650 and shim them up correctly. I would also get rid of the sharp edges in the chamber using a sanding roll, but most importantly I would make sure the manifolds are ported all the way up and not just match ported at the bottoms. |

I have 44x37 wedgeports on my 2332 I built. Out of the box heads and manifolds from CB except I installed VW650 springs and flycut them to 52ccs. Web 86C cam w/1.4 rockers, 10.3:1 compression, 44idfs w/ 38vents, 1 5/8 header and muffler. Made 151hp to wheels at 6300rpm with pumpgas, muffler, belt and no tuning. Stock doghouse cooling system and I drive it to work every time its nice weather.
I think with IDAs and porting the manifolds all the way up I would gain a lot more.

Dom I'm a little confused with the above post. Are saying the Roger's setup reads high by 20% or more? Seems hard to believe as it sure looks like a "state of the art setup" they have at Heads Up? Wayne |

No Wayne. Dom missed out on one comma: .... so if you saying your engine made 160hp, on Rogers it would be more like 130hp, now that I would believe, I have seen it plenty of times.

No, I'm saying Roger's Dyno is dead on. If you want to know what your engine is really making, his is the best, but there is nothing wrong with any of the other dyno's, I look at them as a tuning tool. |

Kevin and Bladey have mean combos with wedgeports and my old engine made 180 also but my new engine with wedgeports feel way stronger so it must be in the 200 mark so that I no like burnout cuz it feel like I could easy break my trans. And if you want a extra one you can get it cuz it all are the same and easy to matchup. No waiting. I like it.
