I am in progress building race engine only. 86 x 94
Case CB aluminum.
Rods 5.7 inch
pauter pro heads 52 X 40
JE piston with total seal
Webcam 277
CB light lifter
Ratio rocker pro 1,6 : 1
Carb would be jaycee 52 or 58

Accidently I received heads with 1.6 rocker instead 1.5.
With 277 and 1.6 rocker valve lift would be arround  0.750" I am worry if the K800 spring could handle the lift. What would be affected to cam and lifters?

Should I go a ahead assembly

Did you actually measure this lift, or is that a typo?

According to my charts, the Web 277 has 0.441" lift at the cam, so that would be 0.705" with 1.6 rocker arms.

With 1.5's, it would 0.661" lift...

I haven't personally check the cam lift. Or see the cam chart.  The owner got the cam with no chart.  And I saw on webcam website states 0.66 lift which i though using 1.4 rocker.
Thanks for that correction..

Web-Cam usually lists their cams with 1.5 rockers.
