    Cool Aftermarket Heads

    I hate to post new threads but i was wondering on which heads would give me the most benefit since i already have tsp cam(233,239,600,603), titaninum retainers, hardnend pushrods, dual rate spings, ps headers, ory, gmmg chambered exhaust, clutchmasters clutch, slp cold air pac, and air-egr delete. So if someone could tell me which heads would be the best benefit for my setup, please provide some intel! Thanks alot!

    It really matters on your budget and how you plan on using your car. Is it a D/D? You have the PRC heads, Dart heads, AFR, ET and a few others. AFR heads are one of the best but cost more. Check Texas Speed. They have a few of them.
    I just installed a set of Ported Dart Heads. I was at 401hp before heads. I am waiting on dyno with the heads.

    Good luck.

    I put down 435 with the Patriot heads, similar cam to yours, and FAST 90/90. They're good bang for the buck, but you'll have to get the Patriot valve seats cause the stock size won't fit. Trick Flow and AFR are the best heads for any set-up, but I don't really see the point of spending the extra grand they are for a couple of CFM more that they were over the Patriot heads.

    Price is really my least worry but i do want the best bang for my buck, you know what i mean? I just don't see the point in spendin 2500.00 for a set of heads when i can get almost the same for 1200.00 minus 2-4 hp. But you know what they say you can't have your cake and it it too, but i will find a way, lol! What you guys run in the quarter ? UTVols98, i'm from TN, just stationed in FL, you from there or not? I put down 385rwhp 370rwtq with hp dyno tune out of Orange Park,FL ! How much hp should i expect from a set of heads such as patriot or afr? I have electronic cutouts and 2005 18" C6 vette wheels coming very soon along with lsx intake and nw 90mm combo! What could i expect after all this?

    I've heard AFR are top of the line, but they are very expensive. Patriots and PRC's have a good price and lots of people run them so they cant be that bad. I'm thinking of going with Patriot personally.

    I went to school at UT. Hoping to move back there sometime soon cause I love it around there. Originally from Arkansas. Now, freezing Minnesota.

    Trick Flow and AFR will be the best but way too expensive IMO. I have Patriot, but either Patriot or TSP heads will be just fine. 435hp and 407tq, that's a little more torque than I put down. Looks like some good heads there.
