i like to use studs on any application where possible, and reduced head flange nuts. i also cut the flange between the pipes, and drill one hole two or three sizes oversize. this allows the pipes to expand and contract as they see fit, ensuring the gasket does not tear then blow out between differences in cylinder temperatures. i stole these ideas from member Mr. P-Body many, many years ago, and they have worked great for me since. remflex gaskets have worked well for me.

I have TTI headers. I don't use gaskets, just a very thin smear of rtv and locktite on the bolts.

Fel Pro 1462 header gasket on the driver's side. Just high temp silicone on the passengers side. I also like the TTI header gaskets. I use the bolts that came w/ the TTI headers.
The reason I use a gasket on the drivers side is b/c the header is sandwiched in there when the motor is dropped in...can't get room to put silicone on it. Much easier for me to just use a gasket. The passenger's side header will fall out from under the car when you unbolt it. Fairly easy to silicone it and bolt it up.

My TTI gaskets work fine along with the SS bolts. If I was to pick another it would be Remflex gaskets and ARP bolts. SS bolts, Not with Alum heads i hope!
