What heads for BTR 3 on LS1 I have had a BTR Stage 3 231/244 in my 2001 Trans Am for a little over a year now and am looking for some more power. Which heads would be best for this cam? I have been looking at TFS220 as cast heads but BTR does not do the valve blending on these anymore.
I wouldn’t be opposed to swapping the cam out for something else but if I did that I would like a cam that matches well with PRC Stage 2.5 LS6 heads to keep costs down.
Currently have stock LS6 intake (don’t plan on doing a Fast intake anytime soon) 1 3/4” Headers, SS3600 stall, 3.73 gears.
Would be happy with mid to low 11s in the 1/4. Not worried about dyno numbers.

You can do a set of 243 heads send them to AI and they have a 226 runner program. They offer a large valve for 4.0 bore but I'm sure that you can do a smaller valve for a 3.9 bore. I would definitley call them, I think they are running 320+ cfm at .650 lift which is pretty stout for a stock cathedral cast head.
Advanced Induction is excellent at porting heads but sometimes very difficult to communicate with and get a response. There's several threads and posts mentioning that concern on the forum like this one.
The last two Google reviews may also raise a concern.

I went with PRC as cast 225s, and I probably would do the same if I had a BTR stage 3. Spend the extra $100 for the hollow stem valves too.
Otherwise a set of ported 243s would work well too. If you have more money to throw at it, maybe TFS 215s or Tony Mamo's 220s

So AI can't respond or communicate with potential customers or customers because they have supply chain issues and are backed up? 🙄

I like AI's products too and have suggested to many folks they (AI) were worth considering over many years but that statement no sense to me.
