What should valve lash be set at with 1.6 full rollers? With S/R torquer heads and stock 350 block would it be safe to say I will have enough piston clearance?

 

I went with 1/2 turn (just the nut) plus another 1/8 turn with both the nut and lock. I've heard anywhere from 1/4 turn to a full turn is OK. You should have plenty of clearance. My 355 is zero-decked (stock is ~.025") and slightly-domed pistons and am running the same cam and 1.6 CompCams Pro Magnum rockers and still have enough clearance. My only problem is that this gave me over 11:1 compression, so I can't run more than 26 degrees of timing at WOT w/out running 104 octane race gas. :/

 

i adjusted mine so that the pushrod had enough tension on it to keep it from spinning and then another 1/2 turn.
