Another one of my heads question

[Makdaddymac]

is there any process for taking old school heads and putting them on a new school block i heard something about drilling for smog but im talking out of my booty....

you could drill for smog, if you plan on meeting emissions. I suppose the biggest concern is in choice of headgasket and lower intake manifold gaskets. the only real difference is in the coolant passages.

is there any heads with a sort of oem fit(of course there is maybe a spark plug problem)....but otherwise just(im just kidding)grab some wrenches bolt-pop and go...
