This is for my Truck a 1993 Chevy 1500 EFI 350

I want to know what is the most Intake Lift and Exhaust Lift I can have on my stock heads.

Also what would be the most a stock valve train could handle? 99% sure valve train will not remain stock just what to know for kicks.

It's a 93 350 EFI

Can any one help or point me in the right direction.

PS I did the LG motor sports GX3 Cam with 114 LSA in my SS and loved it but I was going to put a little bit bigger one in the Truck!
