Tristan,
Hypermax told me only '83-'85 had head gasket issues. They also said my stock head bolts were fine. I run 12-13.5 psi with no problems.

the downside is you will want to crank on it again in few weeks. if you turn it up too far you will have too high egt especially n/a

Head gaskets got better on the later models, but the head bolts are still the wimpy 7/16s instead of the 1/2 bolts used on the 7.3. My head gaskets already seem to be weeping a little on the back sides of both of them. So I am trying to be careful for now.

so if i've got a pyro, it's pretty safe to turn up the IP on my near stock IDI a tad?

Yes, just keep a close eye on the pyro, no melting of pistons needed! My worry is if someone else happens to drive the truck who doesn't pay close attention...
