I want the trickflow 225s, but they only fit a 4.000"+ bore. Is there any other heads that are bigger than the trickflow 215s? I might just get the 215s for my 383 H/C/I set-up. What do ya'll think?

How much more would those make over the patriot stage II 5.3s?

AFR flow > Patriot flow (generally speaking)

AFR $ >Patriot $


I'm not dissing Patriot in any way (just ordered their St. II LS6 heads), just sayin' that AFR's are proven time and time again to be one of the top flowing heads

AFR's are proven.

There are guys on here that make 450+rwhp on H/C setups with Patriot heads and mild cams though.

Patriot cam make a you a set of heads for your application that will flow as good or better than the AFR heads for less money.

I'm running the patriots and I think they're great. I just want something more due to the ported 90mm FAST/383. I didn't plan on running the 90 FAST, just a LS6 intake. That's why I went with the patriots. Just trying to squeeze all I can out of my set-up.

Yours is the case that Tony Mamo of AFR often quotes. You have some ported heads that flow pretty good, but now you are hungry for more - how to get there. Would have been better to get the AFR's to begin with (but like you said - didn't see the FAST coming).

I would ask Tony whether or not he recommends the AFR 225 over the 205. He's made some great numbers with both, but the 225 can lose a little on the low end (and fuel economy) when compared against the AFR 205.

Since you are modding a heavy truck, and could probably use help in both departments, I'd suggest the AFR 205.

They may make um flow the big number, but the power the AFR's make will never be there with the Patriots. It is simply 2 different playing fields. Patriot has always been a great budget head, but they just don't make the numbers that the AFR/TFS/ET heads do.

I'm on the fence on which choice you should make for the 383 Hemi. A Mamo ported FAST and a set of small bore 225's, or a Vengence ported fast and a set of TFS 215's...... Either would be evil on top of that motor, but which one will out power the other will be tight. My advice would be to talk with Tony and Ron and see who the better salesman is.

I've got the Vengence ported F.A.S.T. as of right now. It's a nice piece of work, not to mention the price! If I go AFR 225's, I don't have to buy roller rockers. If I go TFS 215's, I have to buy roller rockers. But, the trickflows seem to be the #1 head right now. Plus I like the 13.5* angle and different angle of the the spark plugs...But, AFR is a proven head...Too much crap to think about! Any advice or opinions are welcome!
