Paging TCG vendors with opinions on this...
I'm fairly certain I lifted a head or two awhile back while pushing ~20psi on the street. Ran a compression check and its only clocking in around 90psi/cyl, a couple as low as 75psi.
I'm running Akerly and Childs Xtreme rings, which were gapped for a medium nitrous shot. I tried finding my notes from when I filed them down to see what they measured, but I couldnt locate them. So IIRC, top ring is .038 and 2nd ring is .042. They were clocked 180* when installed.
Back to the head gaskets... pretty sure I need to get new gaskets. Right now, I'm running ARP studs and GM 6.0L MLS gaskets which were installed dry on a freshly surfaced pair of heads. The studs were installed to ARP spec, but it turns out many people install them with another 10-15lbft past spec... can anyone confirm this?
Not sure about cometic (heard that they have sealing issues if the block isn't freshly decked), but I've been hearing about LS9 gaskets... something about them being 7 layers and "better" than 6.0L 3 layer MLS gaskets.
Thoughts?
