Indy LAX or J-heads?

My old 340 TRW flat tops .020 above deck had 202 Js ported by me and I installed IMM ported LAX heads setup for SFT cam XS274S with only .500 lift. Car picked up .4, I have not run in good air yet, and the cam needs to be upgraded lift wise to take advantage of the head flow. I was running 12.05s and ran back to back 11.77 in 1000 DA. I think it will run 11.5s this winter in good air without changing the cam. Save your money up and get with Brian when it's time to get some new heads.
