Default Heads Suggestions For F13 Cam???

Just starting research for the direction to take on a solid set of heads to go along with my mods in my sig and my new Cam setup. Im attracted to a responsive type setup with heavy midrange power. Please offer up specific routes to take and your .02 cents on why it would be a good choice or WAS a good choice for you if you have a similar setup. Thanks again!

243 ls6 heads is the way im leaning both for price to benefit ratio and common practice....but I would really like to hear from some of you guys with similar setups. seems like searching keeps poping up this combo but not much in the way of numbers or results. Thanks again guys....lots of views...lets hear some imput!

What's your budget?

If you have around 1300 or so, you can do either Livernois LS6 heads (no core), Ai Ported LS1s (your core), PRC LS6 with stock valves (no core), PRC 5.3s (no core), or TEA heads (your core).

I'd probably either do the AI HCR 219 option or the Livernois LS6 heads. Both would work well with that cam and make a ton of torque in that ~$1300 range.

If you want to step up to $1600 or so, I'd look at PRC 225s or TFS As Cast 220s. Both make insane power.

Thanks for the starting point! Saving the $1300 may be a little out of reach for some time. Are the LS6 heads worth the $400 id probably have into them...with appropriate springs and support? What kind of gains would I be looking at with the ones you suggested vs a set of ls6's?

The biggest issue with spending so much on the heads ($400 vs $1300) is that I would feel like it was a waste if I didnt upgrade to a FAST intake as well....Wich as you know is going to cost at least the around another $900 on top of the $1300 for the better heads....at least with the $400 heads I can get away with the stock intake or at least settle for an LS6...what do you think? Tq monster sounds pretty attractive though I must say lol.

LS6 heads are worth about 20HP.

Most of the heads I listed are worth probably 50-60HP.

FAST is worth around 15.

If I keep my car ill either go AI 226, PRC as cast, or tooley touched trickflow 220's. My car just made 420/400 with 243 ls6 heads and BTR springs, so there is definitely room for improvement with heads. I'm running the f13 also so there's some food for thought.

I have the F13 and 243 heads on my 99, pretty stout for a low budget setup, picked up the heads from another local member that spun a rod bearing in his Trail Blazer SS. I had the heads cleaned up, milled around .020 and valves lapped. For springs I used BTR platinums and BTR pushrods...
