350 stock with pistons with the same 083 casting heads ported to match a performer RPM intake with manley double spring valve springs new valve seals and valve retainers and a cam that makes power to 6200 rpm's is this ok? or should i get screw in studs? the cams lift will not exceed 510 i just havent decided on which cam yet oh and its bolting up to a th350 373 rear end gear posi 1900-2100 stall.

 

Studs are not about lift. Run as much lift as you have the springs and clearance for. Studs are about pressure. Multiply the open spring pressure by the rocker ratio. If the result is over 450, then you're past the practical upper limit for pressed studs.

 

ok so i have no clue what pressure my springs are cause ive them for over a year but my rocker ratio is stock so what is the stock rocker ratio also how much lift could i run?

 

stock rockers are 1.5:1
