small block heads, 4027596 casting # any good??

LOL. You see, I can explain it. What hasn’t happened is YOU have not explained why YOU want to use some crusty old casting, rather than start with something better.

I’ve already posited why you do it. You think it makes you smarter. It doesn’t.
If you could explain it you would......

Why do you care what I want to do and with what?

Bye bye. You aren’t worth bothering with.
Does that mean you'll stop posting.....:lol:
