Which heads are best

What cam specs do you have with that?

I will dig out the cam card and post them. I know off the top of my head it is 255/255 @ .050 and .620/.620 gross with a lash of .014/.016 hot on a 105 LSA.

I don't have the rest of it memorized so I'll have to pull out the engine file.

BTW it is installed at 105.
