340 Piston to valve clearance w/RHS heads

Those are for a 4.00 inch stroke (stroker kit), not the stock 3.31.

Summits showing the TRW's are still available.

This is what I recommend even though you say you don't want hyper pistons:http://www.kb-silvolite.com/kb_car/performance.php?action=details&P_id=135

I used KB hyper's in my 360 for years, stock crank, stock rods and went 10.50's. Now the rotating assembly's in a customer's 360 he street drives.
All I can tell you is don't be afraid of them. They are light, have plenty of valve pocket, just open up the top ring gap and let it EAT!
