I doubt 400rpm's will present a problem. Someone correct me if im misled in my assumptions.

hmm, chris.... what would you suggest for just a head build.

ca18boy, i think i'll take you up on those valve seals. e-mail me at [email protected].

i kinda doubt i am in need of a full rebuild so i'm jsut gonna replace the head gasket and install some arp studs. i jsut wanna know what else i should do while the head is off.

block honed with torque plate(i have one)

Can I still re-use the stock pistons if I have this done? I was going to get new rings.

yeah, a really light hone will work with stock pistons. just a head build would be likecometic head gasketarp studsrocker arm stopper(must have)lap the valves(easy and cheap to do yourself)or 3 angle valve job(around $150 at machine shop)have guides and seats checked at machine shop. that may be the best $20 you ever spent. valve seals

Hey Chris what was that torque plate that you mentioned? Does it have something to do with the hone?

I wanted to know what a torque plate was too...

i googled and got this Cylinder Boring Tips

Lightweight block castings have become very prevalent in our market. Since the overall mass has been reduced, the controlled stresses have become an important factor in the block's integrity. To ensure integrity, we must recreate that stress by using a Torque Plate when boring and honing.

Always begin by torquing your main caps in place to correct specifications. Next, install a torque plate and torque in place using final assembly torque specifications. Also, we recommend using correct length bolts. If they are too long or too short, they may abnormally stress the block. The future will even dictate correctly torquing all external motor mounts and related accessory brackets.

Allow .003" minimum material in the cylinder bore. Remove broken and partially severed material by honing after the boring operation.
