Thats not bad at all. Gotta throw some "extras" at it while yer at it. Id count studs as nessecary. Always upgrade while replacing, at least thats my guidline when wrenching on anything.
Ammo, if u really want, just get a basic rebuild kit, gaskets, rings, bearings, and while your in it, I would invest in a cam as well. For the piece of mind, and from what I have gathered, its a great investment. Maybe take the block for a hone job, polish the crank, n balance everything. Maybe if you can do it, do some port matching on the head. :rockwoot:
