Air Flow Around Valve Guide
Yep....close by for sure! Back when we had a good Mopar show at Bristol every year, I sold a Challenger to a guy in Kingsport. There's quite a few Mopar guys in the Tri Cities area. My :realcrazy: sister-in-law lives in Johnson City, so I'm over that way semi often.
I got a pair of Speedmaster small block heads during the Black Friday deal, and when I was looking at them I wondered if there would be any help for them around the guides. They leave a big ol knot of brass hanging into the bowl, for sure!
