Hey guys I have $2000-$2300 to spend on heads but don't know or think i need to spend that much for the best power gains. I have mods in sig and will have FAST 92/92 along with a Futral Motorsports F-14 Highlift (fly cut pistons). I was thinking Advanced Induction LS6 heads.. BUT Trick Flow might be the right decision ? Help me figure this out guys. My car is not a DD but does see some weekend street abuse. I will be at the track also. Thanks!

 

Trick Flow gets my vote. Probably the 215

 

You defintely can't go wrong with the Trick Flow

 

The TFS 215's Flow Better than the LS6 Stage 2.5

Flow Data

TFS 215cc LS-1
Lift Intake Exhaust
0.1 66 54
0.2 138 118
0.3 218 187
0.4 272 231
0.5 308 252
0.55 318 258
0.6 324 262

 

OK it sounds like the TFS 215's might be the way to go. So who has the best price on these ?

Also, should I just use these right out of the box or do they need any port work ? What about springs ?

I'm going with the Futral Motorsports F-14 Highlift cam and am fly cutting the pistons. Should I mill the heads a little for more compression ?

What pushrods should I go with ?

 

TFS heads are $2400 plus another $4-500 on a set of roller rockers. I purchased a set of stage 2 LS6 heads from TEA that have similar flow #'s to the trickflows for $1800 which would leave you a few hundred left over.

Hey thanks guys!

Something else for me to think about:


And just something to think about, TSP Stage 2.5 5.3L heads would make very similar power - and in fact have done right around 450-460 with an MS3 (just about the same size as a VRX5) and stock FAST. Mill those heads, port the FAST, and run the thinner gasket and you'd see 480 out of those combos too.

 

I have those heads and I wouldn't mention them in the same breath as TFS, AFR, ETP/Performance Induction or even the TSP 215's. They are nice for a budget head but comparing them to a proprietary casting is apple and oranges.

LMAO at 480 on 5.3's

 

I would just have your stock heads CNC ported. They will flow the same if not more than the aftermarket heads.

 

Trickflow 215

 

TEA ls6 stage 2 or better. It will save you a substantial amount of money. But trickflow are great heads.

 

My opinion on how heads stack up as far as performance goes..
Tickflow 215s
TEA stage 2 ls6
TSP 215/227
AFR 205
prc ls6 stage 2
I personaly would not buy 5.3s but thats just me, i agree with SOMbitch i think 480 with 5.3s is pretty funny too.

 

Ron@VengeanceRacing is an authorized dealer for TFS heads. He can also answer all your questions. The heads and RR's will be a little above your budget of 2300 though. Save for another month and then pick them up.

 

He might wanna go for some as cast TFS 220's. Within a few cfm's of the CNC'ed and $2100 will get them including the rockers........

 

I agree but the OP did say "BEST" and IMHO TFS 215's would be best.

Picking up the "as cast" tfs 220's would be a great second option. Save a few bucks and only lose several hp. Fair trade off.

Keep an eye out for people selling heads. V Series Tech just sold a set of afr 205's for 1800.00 shipped !! Great deal ! They were completely freshened by AFR and hadn't been re-installed yet. So keep your eyes open in the F/S section as well, good deals.

 

Brian @ TEA can "touch up" the 220's for a good deal and still be within your budget. I was going to go this route but totaled the car. Deck the heads to your desired compression and you're set.

 

TFs. If you got the money thats the way to go.

 

i would buy some LS6's and send them to brian @TEA and he will get you what you need

 

KY-turbo is running a sale on TFS, priced lower then most.
