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.

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.

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