I heard you can run into issues with the eyebrows being to small to accomodate 2.02 valves??
Any input would be great. Thanks in advance.
PS: cam I wont to use has following lift......int .54 / exh .562
Besides the raw lift, the cam timing
and additional advance/retard has an effect as well. There are so many variables that it is hard to guarantee anything when it comes to valve to piston clearance. I would definitely mock this up first and check the p to v.
is a page on things to check.
Stock piston valve reliefs need to be checked and clearanced if needed w/2.02" intakes. Aftermarket pistons tend to have more generous reliefs.
