400/450 stroker....Cheap parts, lotta work.
I've run 2.25"/1.81" valves in factory iron heads before. This time I'm using 2.20"/1.84" valves. I wonder how much cylinder wall to valve clearance I have at .700" lift.
Intake valve..........
Exhaust valve............
As the plan is to run about .550" with a solid flat tappet we seem to be really safe.
