MikeB, 302s went from 2 bolt main to 4 bolt also, those were very stout.
The one's building 305's can't use quite as big of an intake valve as the 307, as was mentioned.

I agree. In some forums that discussion could get quite heated as I've seen. The original 305 in my GMT400 developed a cracked block in the lifter valley at 30K miles and I was done with 305's after that.
I've tried to sell this engine on CG and Marketplace but no takers yet. It has some good parts in it. I think I will post it here as well since I'm going to have to move soon.
