Well I planned on throwing in roller rockers. I plan to do heads at the same time as the cam. Either leaning towards TFS 215's or PRC stage 2.5 ls6. Either way the heads would have dual valve springs rated to .675 lift. That being said would the cam with the higher lift and lower lsa yield adequate gains over the cam with lower lift and a higher lsa?

I think it would gain some, but I like the slightly lower lift and a stock rocker. Too many of the rollers break and its just an extra expense.

Well that would save me around 400$ if i kept the stock rockers. I could also save 50$ by not upgraded the springs to .675 lift and keep them at .650.

Any thoughts on those 2 heads? Is it worth the extra grand for the TFS?

The car is mint with 18K. It barely gets driven and I really dont intend to drag the thing. Couple times down the track to get some numbers and thats it . I just want the power there for whenever I feel like hauling ***

If that extra grand were to net me another 20 rwhp I'd probably go for it but other than that I wouldn't bother.

TFS are nice, don't get me wrong. Don't know if I'd spend an extra 1k on them honestly though. I went with stock 799s ported by AI.

Default Cam results finally in

Car is M6 and has Blackwing intake/ported stock TB/Kooks longtubes and x-pipe/Corsa axleback. Ed Curtis custom grind variant of the streetsweeper HT/ATI 10% UD

Had it installed and tuned @ New Era Performance.

Car put down 407/381.

I must say I'm very happy with the results.
