Would there be a problem wuth running vortec heads on the 307, even though they were designed for a larger bore? Has anyone done this?

 Im not sure what kinda money you have or what your trying to do. But summit sells a really nice set of cast heads. they are made by dart with the summit name on them. 2.02 1.60 ss valves. for $650.00 i dont think you could get a set of heads built for that. Summit SUM-152123

I finally got over here!!

I will pack off a 307 while stepping over a 305!

Don't dis the 307 b/c I can drop back to a 3" crank and hop it up and go big engine hunting!

I'm talking about shifting her up at 8, 9 and maybe even 10,000+ rpm, big engine hunting..
