Whats a good head gasket to use when installing a new set of heads.... Maybe a thinner gasket to bump up the compression a wee bit???

 

A thinner gasket can be good, it just depends on the application. List all the details of your setup so we can make a good recommendation.

 

GM hot cam, ls6 intake, ls6 heads<--- ((i may get some work done on them... i dunno yet)) LT's, y-pipe, SLP LM1, and a few other bolt on's. SLOW haha

 

::bump:: ???

 

i went with cometics. i think they're some of the best and some say reusable .... have a lot of different thicknesses also. also no cleaning if you take them off like the stock graphite mess.

 

I use GM MLS, but my heads are milled to 59cc..You can get them pretty cheap. I Think i paid $36 for a set shipped to my door.

 

If you aren't having the block resurfaced then GM MLS is more forgiving to imperfections. The cometics require a flat surface and specify an RMS range for the machined deck finish. Most people use them without issue, but a few have had sealing problems. With your cam you really don't need a large bump in compression to achieve optimum results, so I say mill the heads to 59cc and run the GM MLS.

 

Thanks guys!

 

The Cometics are $150+ IIRC and I musta got ripped on my GM MLS cause I think I paid $58
