What are you hoping to do with your? The 6.0 heads are usually used for turbo/supercharger or large cubic inch engine applications.

don't waste your time! If you want more compression, have your existing heads milled.

sounds like you should be in the 12 sec club

Yeah, if they're iron heads, get rid of them. Waaaay too difficult to machine. If 12's is your goal, look into changing your cam(open to debate), get a bigger stall(IMO, 3200), and some long tube headers.

Very true!

xturboguyx2001

12sec club. to easy. set your goals higher. he is right i would go for a cam ,stall & headers! that will get it ib the 12s with a good tune & the rite cam. for the amount of machine work cost of parts vs. gain dont use those heads alum. or not! by the time you get out of the machine shop you will be way over 500 bucks. maybe a 1k. good heads are not to bad a price these days but, with out a good cam & headers you wont benifit alot.
