I have a TR230 cam I going to be putting in my Firehawk along with LT's, LS6 intake, U/D pulley and P/P TB.

I am debating on getting a set of budget heads, probably PRC 2.5 5.3 or LS6 heads.

I did some searching last night and found some threads w/ people using the TR230. One guy put down 440rwhp with stock 243 heads. IMO that's a lot and seems like a freak to me. I have seen several people put down close to 400rwhp w/ bolt ons.

Thanks for any input.

Yup, stock LS6. I think any head will work well with this cam as long as they aren't hogged out huge runner heads. I had great results with both stock 241 and stock 243 heads. I would check out Advanced Inductions CNC LS6 heads with stock valves. I plan on having them port my heads like that so I can keep the lightweight LS6 valves and keep a small runner size. Good luck,

i run the X1 similar to the TR230. and ive been back and fourth deciding on 5.3 heads or some LS6 heads. but i am leaning towards LS6 heads.

How much coin are we talking about?

I know TEA does some good stuff too.

I have read several places that 243 heads will give 15-20rwhp over the 241. I am going to assume that number will be a little bit bigger with a larger than stock cam?

Call the sponsor of choice and ask them what they can custom taylor to your reverse split cam. Not any head is going to work well with it. Trust me, been there. Done that.

That I didn't know. What are some that work better than others?

I will call some sponsors this week.

Heads that move air instead of advertising flow numbers

i put down 405 RWHP with PRC LS 6 heads. I didnt have the money for Cartek or TFS heads at the time. all in all im pretty happy with the street manners and power of the car on the street. then again, it also has a bottle

Splatt,

What else have you done to the car? Any track times?

SPLATT

its a TR230 with the PRC LS6 heads. no milling. it has 42 LB injectors and a walboro pump. I am missing a couple bolt ons (Ported TB, UD pulley, EWP) everything else is there though, as well as supporting mods for the cam (ported pump, springs, etc...). the exhaust is LTs with a catted Y into LM1. i would love to go catless true dual which is my plan for the future. the car also has a hybrid wet kit with 100-125 jets in it usually.

Sadly, i haven't gotten the car to a track yet. Southern california is garbage for any decent tracks. A couple hours away is Fontana, but i have been so busy i haven't gotten up there yet. With some times and a decent launch i think i could see some good times out of her, 10 bolt willing, lol.

I spoke with Thunder Racing and they said AFR 205
Texas Speed said their LS6 2.5 heads
I talked to Tooley at TEA. He was the only one that said with the reverse split cam the exhaust port is really important. He suggested their stage 1 or 2 ported factory heads or the as cast Trick Flow heads, but I would have to buy rocker arms. At that point I would have almost 2grand in the heads.

Damn good numbers.

I would think a guy with a good set of heads could hit 430-440 but maybe thats being hopeful.

i would definitely like to see some results with AFR 205 and a reverse split cam.
