I'm currently running B8EFS plug on about 21psi and E85. My cold start driveablility is poor until is warms up a bit which tends to be like that with 8's.
I'm wondering if it'd work ok still running a 7 heat range instead? I'm running 9.5:1 compression ratio and 234/246 .612/.615 115+3 cam specs.

7s should be fine. Try them out make a pull yank a plug and read it.
