i have a set of 430 heads from a wildcat and i was wondering if it fit my 72 buick electria 225 455..thanks
They'll bolt up, but...the oiling system is different on the 455, and will require different pushrods because of the different rocker design. I can't remember what it takes to make the earlier heads accept the later rockers, but it can be done. The question would be why; the truth is the later heads are much better. Before you spend a ton of money doing a transplant, get the 67 heads magnafluxed and checked out for cracks, these were very prone to it, especially the 67 set.
