Hi everyony I have looked on the forms and can not find any info on what I want to do.
I am installing new cams on my 14 GT,I have the heads off as of know(block is still in the car),I was going to get them cleaned up and put in new Boss 302 springs.I was able to score a set of Gen 2 heads that have a been ported and polished new springs valves for very cheap cost.I know the Gen 2 have bigger valves and the pistons have bigger valve cutouts .My question is would the Gen 1 valves fit in the Gen 2 heads,the pistons valves and valve cutouts are smaller on the Gen 1 small block.Any help would be great
