Have the heads Re-surfaced no matter what you do. If you want to use MLS gaskets you need to surface the block also.

Use the ARP Head studs, 3.8 specific may require grinding on the exhaust manifolds, chase the threads in the block with the appropriate size tap. Or use the Chevy 2.8 Head studs, same diameter but they are shorter, less expensive and clear the exhaust no problem.

I'll add that the best resource for SCs is over at SCCoA - www.sccoa.com/forums .

(Oh, pipe down! I keep pointing people HERE for non-SC stuff over there!)

Gotcha.

These are non-SC exploded view diagrams, but will give you a general idea of what you'll find: http://forums.tccoa.com/showthread.php?t=138288

It's a basic rundown. It is most certainly worth the money to invest in one of these... you may want to consider getting one: http://www.ebay.com/itm/1990-FORD-TH...#ht_500wt_1180

You don't need a valve spring compressor to get the heads off. Suggest buying a Haynes or Chilton repair manual to get most of the info you are seeking.
