I'm also interested in a set of the stage II's done with LSA castings to go on top of a 416 LS3 stroker with a cam spec'd by Ed Curtis or Martin @ Tick. Also interested in a ported FAST 102 to match the heads.
Would the Mantic street clutch you have on sale hold up to a combo like this? It'll be a street car. Probably only a few trips to the track to see what it'll do.

Would it be possible to see flow bench comparison between your stage 1 heads and a stock LS3 head both on a 4 inch bore. It would be interesting to see how a the small unshrouded valves flow vs. a large shrouded one.

I currently have a stock cube LS1 with headers, true duals, HPE S Cam (238/242), th400 with 3600 stall and am looking to get some better flowing heads on there ( still on the stock 241's).
Was wondering if i would have any PTV issues with that cam and these heads?
Thanks!

So there is a very good possibility you would be fine, but we would want you to take the necessary measurements before final assembly.

PM Sent...We've used Ed's cams in the past and recieved awesome results and I know Martin's cams make a lot of power and a lot of happy customers, so you can't go wrong with either. Yes, the Mantic Street would be a great clutch for your setup, it is rated at 550 ft/lbs at the wheels and will take quite a beating, definitely recommended.
Not too often these days do you see other vendors go out of their way to say something nice about another vendor. Big kudos and respect sent out you guys way!

Sorry, no track times or dyno numbers. If I get any, I will post them up as soon as I run.
However, I can tell you it definitely picked up every bit of 40-50 rwhp just by how I am running against cars that used to destroy me on the street.
Ran an 11.6 @ 120 car pre heads and he absolutely killed me, just flew right past. Ran same car and we're about even with me inching away as the speed got higher.
Overall, I am happy with the setup as it is a pretty budget friendly setup. I am still running manifolds after all. I do wish I had a little bit bigger cam in there though, the 224/230 is a little small for my tastes. I may try the spinMonster 230/234 grind.

These are very nice heads. Had I known about them when I bought my heads, I probably would have thought long and hard about them.
When I talked to Ed Curtis, he tried to steer me to the Mast Black Label LS3 small bore heads. But frankly, the cost was outrageous.
The cost of these from Ballistic Speed + stock LS3 manifold is a very good deal (and I wouldn't even bother with the FAST on an LS3 - it's good for maybe 5-7HP; nowhere near the 15-20 you see on the LS1).

During fall/winter I am either gonna put a real cam in there or put a blower on, have to see how the funds look!
It is most definitely a 120-122 trap car as it sits, not bad for basically using all factory parts. Factory exhaust manifolds, factory intake manifold, factory heads. The only thing truly aftermarket is the camshaft. In a DD, I prefer most of my parts to be factory. Well, I guess I should say "factory" since they come from different model vettes .

The intake port is where the major difference is and requires Ls3 type only components.

Thanks for clearing that up. I know these heads necessitate a LS3 intake, but wasn't sure on the headers. The only reason I asked is because someone who posted above said they are still running the Vette manifolds, so I just assumed their long tubes couldn't transition over.
