2.02 intake valves on a 305 will not work without some mods....plus once you mod it the valve will be shrouded too much.....stick to a 1.94 valve.sigpicTurbo Charged LS1/T56

gain more top end, but lose a lot of low end plus torque.
Tell him to save some $$ for that 350 swap.
That's what I did. If I had heads with all the mods I did to my 305, I'd add about 50hp. 305 heads are a bottle neck for sure.
But I'll save that money for my 350. It will be money well more spent.
Whats he looking to do? I can suggest a few Ideas. There's a lot of $$ in my little 305 already. But I can at least swap that into my 350.sigpicComment

305 also uses a rather small combustion chamber so most heads will lower compressionComment
