McBee ... They have good Quality stuff .. I use McBee in all the Detroit 8V92's and such ... even the Series 60's ... No blow outs and no leaks .. they have done away with the Rubber O-ring in the S60 stuff and gone to an embossed copper type of ring ... Works awesome , Now to fix the 11.7 kicking out the rods @ around the 400K marker .. that gets real spendy fast ..

 

OK, I'll try looking them up next time... I have my old engine my buddy wants to use, and he wants to put a new HG in it before it goes in his truck.

You think it's a bearing problem or a rod bolt problem that the 11.7 throws the rods out? That sure is an expensive fix (if you have a fix)

 

Been running a felpro headgasket in the puller for 3 years now and never had a failure, video of the truck is in my sig.

 

Well its a pood design of the Rod bolts i beleive ... and the fact that the engine is 40' behind the drivers, ya dont know it knocking till its knocked out ... LOL

 

Cometic MLS Gaskets

 

they dont make a MLS head gasket for the 12 Valves..... but some say the 24V gasket can be worked to make it good ...

 

i bought a .062 thousandths thicker, layered cometic head gasket, in which its rated to handle 60psi of boost, and i studded the head using 12mm (arp 2000 studs) but im only going to run 43psi or 40. so i should be safe

 

why did you get a .060 over headgasket?

 

I cant spell the places name correctly i will get it and let you know, but the place took 4 weeks to special make it and was over a 300 dollar gasket,they build gas engine that run alcohol and the same material they use on those 1200hp gasser they made me a special hg with the same material its crazy, iv never seen a head gasket look like this one,seems very stout,ill get the companys name for you.

 

That would be the Cometic MLx Gaskets, they make one of the best race gaskets around. And they do make one for the 12 valve, just ordered one yesterday.
