Whats the best website to get a thicker head gasket

The head i just got has been milled and i need a thicker head gasket.
And i do not want to spend $300 on this gasket

eBay! Did you check SBR? FP? Those are just about the only 3 places I would buy from. Tuners has a list of shops, I would check them out.

Took a while to find it lol. I knew I had seen it before, just couldn't remember where. Comes with new ARP headbolts, Cometic MLS head gasket, and complete valve cover gasket kit for only $189(6bolt) or $202(7bolt).

I'd go with a cometic head gasket from SBR; that's what they put in my 6-bolt and I've heard good things about them.

So should i stay away from the 4 layer metal gasket? How thick are the head gaskets from http://www.thespeedfactor.com/dsmtuners_promo.html
