Shawn - you probably already know all of this, but just get an L36 shorty - you can get them for ~$250 all day long.
Tank it and polish the crank - ~$125-ish
Deck it - ~$75-ish
Resurface heads - ~$60-ish
Valve job - new seals - ~$150-ish
Clevite bearings (yes) - ~$22
Main bolts (I wouldn't mess with studs - because if you do, then you "should" get it align-bored, too.) I would use studs for the heads, though - and I did.
Mains - ~$50
Head studs - $80
Rod bolts - ~$100
All new gaskets/seals, etc - ~$170-ish (full gasket set from ZZP is $160)
Cam - gray area here - VS or XP is tried and true, but it's all about preference. ~$320
Diamond 9.5:1's - ~$700-$900
I've already decided that my next GP will be turbo.
