    Tsp Stage 2.5 Or Patriot Stage 2?

    Looking to buy either patriot stage 2 or tsp stage 2.5 heads. Kind of leaning towards the tsp's. Also in an auto car with headers, full exhaust, 3500 stall, ls6 intake, 3.23 gears what would be a better cam? tsp torquer 2 or 228r? Not a daily driver, just a weekend cruiser but still want decent manners and mileage, but would like high 11 sec quarter mile times. any ideas? thanks.

    With your mods, the 228R cam and the PRC Stage 2.5 heads should definitely get you in the 11's with a decent launch. Both cams should have good street manners with a good tune.
    2002 Camaro SS M6, 2.5 PRC 5.3L heads, TFS 228/230 cam, FAST 92, bolt ons + a 10 lb bottle in the back.


    1989 Corvette L98, A4, Full bolt ons, etc.

    Ls6's that you can have milled to your deisred CC size. i fail to see what the point is for installing smaller sized heads to bump up C/R when you can do the same with Ls6 heads...

    im running Patriot Stage II heads 59cc...

    The same chamber volume can be obtained from the LS6 heads as a set of 5.3s. But you'll give up a significant amount of valve clearance to do so. Some people don't want to cut pistons.

    Also by cutting down the LS6s you reduce an already thin deck... for people running nitrous this is less desireable. The thicker deck will always seal and stay sealed better.
