Building my motor now. What head gaskets do you guys reccomend? Going twin turbo with around 18-24lbs and gonna be shooting for 1000 hp. What head gaskets should I use. Thanks in advance.
What head gaskets??

My machine shop does a lot of high hp builds. He uses the ford racing head gaskets (ford racing will tell you they wont fit a cobra for some reason). Other than than he'll use a cometic if the heads have been decked and he needs taller gaskets.
Cometic MLS is what the shop uses on Modular builds.
The Cometic MLS should be fine under 30psi. If you running 3.700 big bore might have sealing issues above 25psi with MLS
That's what I used when I built my boss 5.0 modular last year.
Got them from modmax racing

One of the nice things with the Cometic brand gaskets is you can play around a little with static compression by getting a thicker or thinner gasket
If you run more than 30 psi you should consider running the copper head gasket with o-ring installed in the head
Accufab has the copper gaskets for the 4.6

I'm not running anything other than the stock eaton and ended up popping the stock gasket on number 2 which it barely was blown just enough to pressurize the cooling system but I went with cometics 51" thick and used trickflow head bolts cuz studs was overkill for all ima do with my car.
Stock OEM headgaskets or the FelPro Blues (much cheaper) Been proven at the 1000rwhp+ level many many many times. I install the FelPros in all of the builds I do and never had an issue.
