I cleared a .566/.566 218/224 cam with 2.02 1.60 valves and stock pistons. It was very close.

I'm not sure about the GT40 heads, but with stock pistons, I ran the stage one just fine.

hrdroc · 01-29-2007, 10:29 PM

thats cool but what size roller rockers did u have USMC302 i have 1.7 roller rockers

We used axle grease to check my P to V clearance on my motor with 58cc heads TFS #1 cam and 1.6 rockers, spun it over, pulled the head off and the valves didn't even have any grease on them!!
And we had it smeared on the piston pretty thick, so I think your OK too.

hrdroc · 01-30-2007, 04:34 AM

all right that sounds like a good thing to do...that is one way of checking it cool thanks man...my total lift with 1.7 roller rocker is .531/.542

We were running staggered rockers at that time. 1.7's on exhaust, 1.6's on intake.
