Ok, im deployed right now to afgan land, but about a month and a half before i left i got my F13 installed in my car along with LS2 chain dual springs and UD pulley, along with a set of 4.10s cause my 3.90s were shot. Anyway, i didnt get a chance to track the car but it went 12.2 at richmond on a warm night, i want deep 11s, and figure i might be in the 11.7 range now, 11.6 at best. The car did 388/385 at VA Speed when Ed tuned the setup. I want to get the most out of it and want to know the absolute best heads to give me the most power. If i gotta save up for the expensive stuff i will. I had a few frineds back home tell me to look at a set of worked over 5.3 heads. I figured too that since the car will definatly be NA i should look at boosting the CR. Any help would be appreciated. If u recommend something please give an explanation as to why so i can understand the advantages. Thanx fellas.

 

If you have the budget, look into getting a nice set of AFR or TFS heads.

 

tfs 215 or as cast 220's is what IMO is top of the line for shelf parts, if you really want to drop some coin look into PI they used to be E.T.P

 

Any particular size? 205?

 

also i guess im lookin for a set of heads that would leave room to grow, later on. Incase i wanted to try a squeeze more power out of them by changing the cam.

 

Bolting on a set of TFS 215's or 220's will make great power now and still make great power later if you add more mods or spray later down the line.

 

im thinkin, should i have done a different cam, or can i still hit 430-450 with a good set of heads. I understand if i was a 6 speed guy i would probabley already of made over 400 and my big *** stall didnt help my numbers, but is it still feesable?

 

Don't get hung up on the dyno numbers man, track times are what really counts. Put the heads on and see what your ET's drop to.

 

i know i know, and i always told myself they didnt matter, especially being a stalled auto, i would just like to know i was a heavy hitter in the HP department. I havent even run the car at the track with the f13 yet. But i have an idea of the times ill run and they already bore me. If only my wallet could keep up the demands i place on my car and myself! I still want to do a 6pt cage, welds and new interior and know i want heads. Its never ******* ending.

 

as long as i can hit like an 11.7-.6 then im sure i could maybe push an 11.4 with a stout set of heads, then i need to figure out how to make more power na, maybe a 90/90 setup if i go TFS heads?

 

Yeah, a 90/90 will definitely make for a nice improvement on a H/C car. Should net you another 15-20 rwhp. You might also consider 1 7/8" headers if you don't have them already. A nice merge collector like a Flowmaster 2-1 merge in your y-pipe (compaired to the usual shitty merges like the Pacesetter Y-pipe) with an electric cutout or going with true duals w/ an X-pipe will also make for some horsepower gains.

 

i so want true duals, but i have a tunnel mount TA so it will have to be a custom job, but thats ok i guess. im runnin slp LM1, TSP catted-y and pacesetter LTs, i def want to upgrade the whole exhaust to something a little less begginer.SS.SLP.LS1, I need to stay in touch with u, u have alot of good i deas man, and im definatly lookin to squeeze every ounce out of my setup as i can. I really appreciate it!

 

so a nice set of 220s maybe?

 

you can get the tfs 220cc heads milled and shipped to you for $1680 from vengeance racing.

 

holy ****, thats badass. thanx alot man!

 

wow, so vengance is pretty sick with the pricing! Wish i took notice of them sooner. Do they have alot of good feed back on theis site? I would guess so looking at the cars on thier web page.

 

so i just want to be sure, a milled set of TF 220cc heads would be a good choice for my power goals right? I want the most out of the car i can squeeze. Also assuming i did get a set of heads like that, would i be able to run the stock ls6 intake with no problems for awhile? Im sure the answer is yes to that question, i just want to be sure.

 

Yeah, they are great heads, and yes, you can use your LS6 intake for as long as you like.

 

thanx alot fellas, appreciate the feed back. Also, i wass on vengance, and i noticed that they dont even list a 90/90 combo, just 102mm tb and intake. Would that be to big? I know other sites probably have the 90mm i was just so impressed with the price of the heads i wanted to see what they had for prices on the intake.

 

I would look for a good used FAST 90/90 set up for a good deal before I bought a brand new 102/102.
