TEA vs. TSP l92s.. help
which heads do you think would make more power? i notice that at .600 they are almost identical.
looking to buy a setup very soon and want to make a good choice. i will be going with a fast 102 setup and 1 7/8 headers.

First off the stage 1's from TEA blow the TSP ones out of the water. Are you even looking at the flow numbers? The TEA's outflow the TSP ones by almost 40 cfm! Here's a little hint on L92 heads.. they don't require much, if any material taken off the intake side. Pay closer attention to the exhaust.
That being said, flow numbers don't mean everything. There is a lot about a head's flow design that can't be measured on a flowbench. A good analogy is think of a flowbench as a dyno. Sure car "A" dyno'd more than car "B", but it doesn't necessarily mean it's faster.
I got my l92's ported at West Coast cylinder Heads, by Rich. I am very much happy with them.

JSTRIB-what do you run n/a? I got 10.85 127.66 hitting the rev in two gears,then clutch went so i never got her dialed in.

The race against my buddies 440 was from a dig. I made 525 on street tires, he made 540 with the converter locked on tall MT ET Drag Radials. The best the 440 got at the track was a 10.4 @ 130 on a nitrous tune, nitrous converter and a nitrous cam.

do you think a lq4 with 11:1 and a set of either TEA or WCCH will put me over 500rwhp with the converter locked? i will have all the supporting mods.. pat g cam,1 7/8 headers, fast 102/102, usual bolt on's

Will you be using stock pistons? ptv clearance will be an issue if you are. If you have pistons with valve reliefs, 500 rwhp should be an easy mark. I would especially look into the WCCH stage 3's if you are running aftermarket pistons.

that said, I own the TSP heads and am not happy with the overall performance. At this point, I don't know if it's because of the cam I have or not.....
I have a C5 with an LS3 conversion using eagle rods, mahle pistons. I bought the TSP heads, milled them to 65cc, and am using a 230/234 114 LSA cam. I have LG pros on the car with stock Ti catback. The LS3 intake is ported. I have a vortex ram air intake and volant air bridge.
Here is my dyno graph:

I'm going to try the G6X3 cam, if there is no appreciable improvement in power, the heads will be sold and I'll go another route.
TEA with core exchange: 1095
TEA with no core exchange: 1529
TSP with core exchange: 899
TSP with no core exchange: 1299
Only about a ~$215 difference. I wouldn't say that, that is TOO much price difference.

Honestly it looks like you have the wrong cam imho. What's the lift? GENERALLY SPEAKING (there are of course exceptions to this rule) you want atleast a 5-6* split between the intake and exhaust with these heads. The g6x3 would be a wise choice, especially since you have aftermarket pistons (with I assume valve reliefs).
Even though the TSP L92's are just the budget of budget cnc'ed L92's, you should still be putting out more power than that with a h/c ls3. Those are cam only numbers....

The numbers I'm putting out now are BOLT ON numbers. Cam only cars make more than that....

im not sure if you noticed but the TEA heads come with .650 springs for the price yo mentioned and the tsp heads come with bone stock springs and you haft to add 250 for the springs which brings it to 1550
TEA seems to be a much better head but i think i am going to stick with a cathedral port head and run the tfs 225 or 235's with my 370
