Proven cam for TFS 220?
Proven cam for TFS 220? I am putting TFS 220 as cast heads with clean up by TEA on my LS2. I have a ported FAST 102 combo and all bolt ons. I would prefer to use a .040 head gasket but may have to stay with .052 MLS since heads are milled to 59cc. I need to know proven cams for these heads to make max 1/4 mile HP/TQ. I did a search but nothing definitive. I have also consulted several trusted sources for cam specing but want to get more rather than less opinions. I know there are alot of very technically intelligent people here so please give your opinions.

Cajun,
I felt my LS2 needed a newer lobe design cam and went with a 235/239 Comp grind with LSL lobes, the cam has 13 degrees overlap so it is a bit rowdy and has some bucking between 1300-1600 but I've learned to drive around it. Look at the dyno I just posted in my thread, the results show my gains of 39/27 at the tires using these very heads with a street tune! My setup was designed for 1/4 mile, look at the powerband.
Dsteck and I will complete the WOT tuning on the same dyno in a couple months, I expect to pick-up another 5/5 easily with some tweaking to the AFR and timing.
