SDPC LS6 Heads are on
Me and my buddy Justin got the SDPC #243 70cc heads on my car.. I had them milled .010" and we lapped the valves in.. I ended up using the Felpro 9199PT gasket for the 6.0L.. I was wondering what you guys think I'll pick up in the 1/8? A tenth or two over the stock LQ9 #317 heads? Here are some pics after another friend Matt (mbaskett here on the board) finished hand polishing the CNC grooves out.. That alone should pick up 6-8 cfm more.. They should flow close to 300 cfm or better at four stages: .450,.500,.550, and .600 . I also swapped from Hooker long tubes to the Thunder Racing 1 7/8 headers during the downtime.. Ran a best of 7.49 before, hope I can get a 7.2 out of it.. I had (DMCRacer) Donald run it, a winner in the Thunder shootout, and he got a 7.37 out of it last time.. I'm quite a bit bigger than him..
Let me know if you have any input... Thanks

I went from a 7.49 to a best of 7.61 with ported heads and bigger headers... I think it's time for some Hals.. I was spinning with 14 psi ET Streets.. I couldn't spin with 18 psi in the old setup.. It was also very cold in the 30s, and it seemed like many were not hooking up well.. Better luck next time..
