Best heads for 346 ? 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!

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.

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.

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.
