Mondo: Put the BR7EFs in, gapped at .038" if you've got a 5 lber. This was Sal's recommendation to me. At first, I didn't like the low rpm misfiring but either I've gotten use to it(they've been in almost 19,000 miles now) or it's cleared up(?). About 500 miles ago, I pulled #1 plug and it was a light grey/tan color with no deposits. I expected deposits because of the occasional misfiring but didn't see any on that one plug. Sal has said more than once that the TR6s are too hot for added boost engs.

Btw, I have 8 Denso IT24s waiting to replace the NGKs but I'm in no hurry as the NGKs gave me my current best et---and 15 mpg as my daily driver.
