Cam for LS2 with TEA Stage 2 heads I'm looking for some advice on a cam to put in my stock bottom end LS2. I am sending the 243 heads for a TEA stage 2 porting. I currently have a FAST 102 with 92mm TB.
The motor will be in a 72 Cutlass with 6spd and 3.70 gears. The car will be used for cruising, autocross and maybe a little road course.
I'm hoping for mid 450rwhp with a broad torque curve. I was looking at the BTR Stage 3, but open to suggestions.
Also, is an adjustable timing set recommended or just the 3bolt conversion with chain and guide?
Thanks

I did read that he started TEA, so I figured one of his cams would be good choice. I'm also wanting the car to have good street manners, so not sure if the Stage 2 or 3 would be the best?

I'm definitely doing the stage 2 porting, I was just on the fence regarding the Stage II or III cam. Talked to BTR and they are suggesting the III... I guess I can't go wrong with a Tooley/TEA combo....

The larger valves are only a few CFM and I'm thinking it's mostly in the higher above .500" lift points
I used to have the stage I's and they flowed like 312 on the inlet side past the factory valves

From what most on here have said; the cost from the stage II porting doesn't create the return in CFM or power over the stage I

I guess its like when ls1tech vets tell noobs like me to use the search feature, when I look at what people are doing with porting factory castings AI and TEA show up the most with documented results.
I just want to spend my money once and have confidence I'll be satisfied.

My thought with the stage 2 was that if I ever did something to the bottom end, I've read where some guys have run them on 402's. I guess if that ever became a thought you have to decide if its just easier to go LS3?
Yeah, Livernois is probably 30min from me. I guess the thing with them is although I haven't heard anything bad regarding LS performance, I have not heard their name come up as often as AI or TEA when it comes to CNC 243 porting. I know you didn't mention it, but I can't justify spending the money for aftermarket castings so an AFR or TFS are not even in the picture.

Katech is close to you as well.....just did a build thread with Katech ported 853s and a little handy work myself....lotsa pictures and flow numbers too
By the time TEA or AI are done (top shelf for sure) you easily get in that 12-1400 dollar range and then Texas Speed or Trick Flow as cast stuff starts to look better as even more power can be had for just a few more bucks....snowball effect if you will and aftermarket castings will allow a larger short-block down the road if the stroker is something you're contemplating

Am I correct with the biggest difference in the aftermarket casting vs OEM is the valve angle with allows greater PTV clearance for a wider range of cams?

I've preached YEARS how badass those TEA CNC ported heads are and people dont listen till they be back on the trailer going home sad and depressed.
Ive seen a set of TEA 243 heads on a 408 n/a run 9.9X in the quarter in a F body.
Anyway those are great results with such a small camshaft that would be daily drivable with ease.
