14079261. Good for port work?

Ive got a set of clean and freshly rebuilt SBC heads casting number, 14079261. How do these compare to other factory heads. Are they any good after porting and polishing? Heads will be used on a sbc to with hopes of the 325-350 Crank hp range.

Also can anyone tell me chamber size and valve size for these heads, Possibly what they might flow? Ive looked at several different books and it only tells me there from an 1986. No other information.

Pretty sure they are 76cc chambers, swirl port. All done by 3500.

Can they be cleaned up with some good port work?

I suppose anything is possible. On a carbureted motor, I would use them only if there was nothing else available.....350, 9 to 1, short cam, tall gear. Remember though, that most all the late model iron heads are short on meat. Many are just plain crack-prone, particularly after someone has been at them with a burr. Personally, I'd use 'em for door stops.

Or boat anchors..

Had a kid bring in a pair that he had obviously spent many hours with a die grinder and stones. "Sorry, they are both cracked" kinda bummed him out..

Thanks for the help everyone. Looks like another set is in order. I've got a set of 882 heads. Or maybe just spend the money for a set of quality aluminums .
