    choices on a good set of heads that dont cost me a arm and a leg?

    Ive got the mod bug and would like to know what heads are the best for are cars? Ive been looking at Texas speed and hear that the 5.3 heads are pretty good. but on the other hand I hear that LS6 heads with a good port job is can be just as good and better? can someone give some input. I have a full B&B exhaust, comp cam 224/230 581/588 114 LSA and tune and only make 383hp and 363trq. I'm wanting 400+... suggestions??

    I use the Texas Speed heads on my V.

    They work, but not cheap.

    The lowest cost option is to have your stock heads reworked. I would call Mike Schmidt at Total Engine Airflow. Advanced Induction also does great work on the GM 243 castings. (About $1,100)

    Another mid-range option is a set Trick Flow 220 as cast heads at about $1,700.

    Finally, if you've got the coin I would look at Trick Flow 215s (about $2,500).

    The Trick Flow heads, and most aftermarket heads for that matter, come off the shelf with bronze valve guides which require aftermarket roller rockers to prevent premature guide wear. However, if you get your aftermarket heads from a head assembler, such as Total Engine Airflow, you can specify powdered metal valve guides that can be used with your stock rockers. (I would recommend the Harland Sharp or Comp Cam trunion upgrade for the stock rockers.)

    (I have the Trick Flow 215s with a milder cam than yours, with a stock exhaust system other than RT cats and I am making 407 rwhp / 391 rwtq on a Mustang dyno.)

    Patriot Performance sells a stage 2.5 stock casting set for $1250. You can always sell your used stock 243's for at least $400 and recoup some of your money. With regards to the bronze guides, they tend to show side wear when used with really high lift cams and stock rocker arms because there is a slight side load put on the top of the valve stem. A roller tip eliminates this load. I used stock rockers with a cam that has a slightly higher lift than your's and they didn't wear out and leak in the 50,000 hard miles I put on that motor. I guess it depends on your definition of premature. I now have a set of Texas Speed LS3 heads that are P&P (Precision Racecraft Components) and they come with the stock guides. I'd give them a call or get a set of the Patriots. The trunion upgrade is a good idea and only $150.

    I recommend a nice pair of CNC ported LS3 heads and change to the LS3 Intake Manifold. Not quite as financially respectful but if you're serious, dump the Cathedral ports.

    LS3 heads/valves require at least a 4" bore. Assuming he has an LS6, since he mentioned ls6 heads above, his only route for LS3 heads that I am aware of would be the mast heads:

    And they definitely arent cheap!

    PRC is the best bang for the buck and they have the absolute best customer service I have found at any speed shop ever. I went out there last September to pick up my rotating assembly and they are some nice folks to deal with. I also have stage 2.5 LS6 heads.
    The stage 1 LS6 heads would be an option. They get the same P&P as the 2.5 and 3.0 heads but have stock valves in them. They still flow some pretty impressive numbers even with stock valves. Here is a link.....
