Hey guess, well I got the 10th Anniversary torn back down again, sold the mazdaspeed turbo setup and now i'm ready to go standalone and GT2860RS. I'll be running 12 psi in this setup, but I have to do some 60,000 mile maintanience first. Well for starters, my head gasket was leaking coolant somewhere so I got the head yanked off the engine I been considering flyin miatas' gasket set, but I wanted to see if any of you guys have a more recommendable option or affordable option... I somehow got the idea when it comes to head gaskets, it probably wouldn't be a could idea to go 3rd party supplier... I probably should just stick to mazda stuff. So what do yall think?

I've made the mistake of trusting felpro too many times to ever trust them again. This is with both my miata and integra. An old friend of mine (a mechanic) told me he swore by felpro. So i've given them 3rd, 4th and 5th chances hoping I just had bad luck. I'll not give them a chance ever again.
As stated, OEM or bust.

Okay, how do you know?
Plus I considered going to head studs vs head bolts, but for the most part my searching the forums pretty much tells me it only makes since if you plan to pull the head off and on multiple times or your running an extremely high output engine...

What is the price difference between studs and new OEM bolts?

If I recall well, all those Failpro are cardboard on a metal frame, the original one is four-layer metal gasket.
Not to brag or anything, but just my experience. On my setup, ran a T3/T4 .50 trim at 15 psi, 550 cc so to raise compression two layers were removed from the OEM metal headgasket. Always ran fine with no coolant leaking with stock bolts.
Before turbo, the car had the two layer metal gasket for about 4 to 5 years when I was N/A.

Some head bolts (mostly older American V6s and V8s) are torque-to-yield (TTY). These cannot be reused.
Miata bolts are not TTY, and can be reused. The factory service manual is quite explicit about what fasteners must be replaced, and they do not indicate that for head bolts.
