the 305 casting # is 14014416 and the 350 head # are 3973487 & 462624 on these casting can you tell me the valve sizes and chamber sizes as well?
The '416 heads should work out nicely for you. They are 58cc chambered and should have 1.84/1.50 valve stock. They have decent port runners, and can be opened up to a respectable size.
I'm not sure about the '487 heads, but the '624 heads seem to come in a variety of configurations. Some might be good, some might not be so good. You might be able to find data at www.mortec.com or http://www.jimsperformance.com/headchart.html
