After 28 years(?) the gasket between the front cover and the engine block has failed and it's leaking coolant from both sides. The problem is this starts a snowball effect of "Well, as long as you're in there you may as well..." And that's what I hope to avoid, but I figure as long as I have to tear it apart I may as well see if I can upgrade the HP a bit without throwing boatloads of cash at it.

So, first, will a set of GT40P heads bolt in with no mods? I've looked at the AFR and TFS...
