Which head gaskets?
 

6.0 iron block, going to go the 408 stroker route and bore it .30 over, what head gaskets would you recommend going with? thanks in advance.

Cometic

6.0 GM MLS gaskets

they will work with it bored .30 over?

With the cometics you can get what ever bore size and thickness you want. You just have to figure out what compression and quench hight your after.

Thanks for the help, who do you reccomend for the best pricing?

Commetic gaskets are great but you need to install them right! They require the surfaces to be done to a certain finish in order to seal properly ( Don't have the info handy ). Make sure you have the machine shop finish the block deck and heads properly or they will leak! Some people still have had issues, I take the gaskets apart and spray them with copper coat.

cometics !!! let me know the size & thickness you want. i have a acount w/ cometic. only takes me 3-4 days for a custom gasket size/thickness. & still get them for less than summit or whoever.
