I know i've seen a bunch of threads where ppl are asking which aftermarket heads are better and once again im in the same situation.. Even after reading all the other post its hard decision for me..

Current setup--
Forged flat top 347
228/230 .571/.573 112 comp cam
853 cnc ported and polished 202/160valves 3 angle valvejob
supposed to flow close to 300cfm
1.8 harlensharp rockers
Vic Jr intake 90mm TB

put down 390hp/393tq , Run low 8.0 consistantly in my 2000 silverado full weight..

I've been looking at TrickFlow's 215cc heads and was wondering where i would be sitting at or would these even be worth spending $2k on them for a 20hp increase??

I know some of you guys have already been down this road thats y i came here for advice

Thanks Ray

Seems like you are missing a few ponies with your setup.

Where do your heads flow 300 at? Is it at .500 or .600 lift?

nevermind, by the looks of your times and not your horsepower number you have a conservative dyno.

.600, ya where i tune and dyno at they tell you real world #'s and what really is going on, they dont play with the dyno to make you happy...
