Head bolts, or head studs?
#11
studs would be nice for pulling the heads in the future since coolant wouldnt flow into the bolt holes, but bolts are cheaper and work great. ive never heard of somoene pulling 1 at a time and replacing it, but i dont see any harm in it.

Foose04 is running the ls9 gaskets and imo is pushing it pretty hard. Also many have been north of 800rqhp on stock bolts so in this build I'd say they're perfectly fine.

Roger, I have a set of Cometic MLS gaskets that would work for you I think. I put Cometics and copper spray on my build with studs and so far not a drip of anything after 3500 miles. I trust these things. I can measure the bore diameter if you're interested.
