That's too much lift for stock springs

By Royce Peterson - 12/11/2002 9:18:17 PM; IP 152.163.188.4

I am running a similar Isky solid cam in an engine with CJ heads. We had to use different springs and the valve guides had to be cut too. I would also expect there to be piston to valve problems if you are running an off the shelf cast piston. I used Ross forged pistons, the valve reliefs are quite a lot deeper and properly located.

The stock springs are not up to much more than .500 lift.
