will adding a milled head (non ported, stock cams) to my car with the jrsc cause the engine to blow? im looking at adding this along with a meth injection kit next summer, my jrsc will only be at 10 psi but id rather be safe than sorry.

What compression are you looking to run?

why raise the compression? its not worth the few whp that you will gain. keep the compression you have especially on a stock block.

he'll be able to answer any question you have on the JRSC. he thinks that raised compression with a JRSC is the way to go, but you'll need a miraculous tune to keep from blowing up.
