Today I scored a used assembled head and (welded) intake manifold that were pulled from a stock appearing 1983 S6 powered pickup and have a few questions, but first the plan:
My plan is to retrofit this newer head and intake along with a regular production, but crack-free (that sounds weird) exhaust manifold on my '66 Coronet. Ultimately this car will be my better half's "fun car" and her idea of fun is driving like a Grandma, so no zoomey-go-fast stuff here. I plan to retain the heat riser and choke functions with hopes to keep it efficient and reliable above all. That said, I'm still pondering the idea of taking a whack off the head to bump the compression, but first things first:
1) Can I use the existing mechanical rockers/shaft assy from my '66 on this hyd style head without making any mods? I read the Engine FAQ mech/hyd differences topic and this seem OK, so if I got it wrong please tell me what I missed there.
2) Is the single barrel welded style alloy intake worth a snot and will it work with the old style exhaust manifold and carb? Should I worry about the porosity?/bubbles in the weld seams on the intake runners or is that a common sight on these things? The bubbly welds really look like crapola and I'd like to smooth them a bit but I already hear Murphy chanting so perhaps it's best left alone?
3) Would it be a good idea to have this head cut to improve the compression a bit or is this whole swap a good idea to begin with for a basic put-put "Sunday driver"? If so (and so), is there a general consensus on what to cut from the head for fitment on my stock '66 shortblock and using nothing better than, ahem, 'premium' pump gas?
Thanks in advance!
