When I bought my used Edelbrocks the only other (aluminum) options were Indy and Brodex. I gave $700 for the heads, then sent them to Curtis Boggs. He charged $1100 to port, do a 5 angle valve job and mill them to 55cc chambers. IIRC they flowed 293 @ .600. I ran them for five years on my 340, 7.24 @ 3240# on pump 93 with a hydraulic cam. When I was building my 408 I sent them to Ryan Johnson to be freshened, the valves were beat so he installed new 2.055" intakes and 1.600" exhaust, blended the intake bowl and did a 5 angle valve job another $1000. In my street/strip Dart, 3260#, 10.8-1, 260/264°, .633/628" flat solid with 4.10 gears it ran a bunch of 6.57's at a little over 104 mph on pump 93. The rockers are Hughes 1.6's that I ground the pi$$ to clear the valve springs. I'm thinking the springs are 2.00" installed height but will have to take them out of them box and measure.

If a guy is starting with nothing the Trick Flow are probably a better value but if he already has the heads and rocker gear I'm not convinced. The numbers from the track I've seen so far from the Trick Flows haven't been really impressive.

Don't the Trick Flows use a rocker with a big block offset? A traditional small type block rocker won't work?
