I'm wondering the same thing, I have the G5x4 cam already and I'm trying to decide if I can swing the money for a set of TFS heads. But I don't want to spend $2,000+ and not make a big difference. Car only made 412rwhp 2yrs ago with 10bolt and 4.10's, but now has S60 and 4.56's. I was hoping to make at least 450rwhp at the minimum.

anyways I don't think TFS heads are even gonna be in the budget, because I think it would be a half decent idea to get injectors and pushrods as well, so I'm leaning towards the TSP ls6 Stage 1 heads at the time being because of price. Plus not quite sure if the TFS heads will clear or not with the X4, I think it would but not possitive on this. I sure as hell would love a set of ETP's or TFS heads though.

I had the g5x3,and x4 cam both with AFR 205 heads. I was on a mustang dyno. X3 cam ls6 intake,1 3/4 kooks fullexhaust,12bolt,m6 stock th-body stock massair. 425.3hp@6,400 387.4tq@4,900rpm's.
x4 cam and stock F.A.S.T Intake 90mm,a GM truck 85mm massair. 456.9hp@6,500 400.5tq@5,000rpm's closed cutout. Open cutout 463.6hp@6,600rpm's 414.8tq@4,900rpm's. All these #'s were on a ls1 346ci motor 11.1.0 compression with forged pistons and rods. On a T.N.T 150shot of spray I got 590hp and 600tq. I'm glad I kept my old dyno sheets.hope this helps ya.

Old thread back from the dead. Check LG Motorsports website for G5X3, G5X4 results with AFR 205s. You will see quite a few dynos in the 480-510 rwhp range. For Trick Flow numbers, check the Vengeance website or do a search. Their Vindicator cam is very similar in valve events to the G5X4 and the MS4. You will see half a dozen heads/cam dynos over 500 rwhp.

anyone know or not if the TFS heads and G5x4 will clear or not? This is my biggest concern really, I know its up to me ultimately to check it in the end, just wondering before hand. I wasn't planning on milling them at all.
