Trick Flow small block heads

It's good for everyone to see what a proven combo looks like.

I'll give you my .02 and remember what you paid for it.

If it was me, and I had someone on the line to buy the Eddie heads I'd do it in a New York second. I wouldnt care of the car didn't go any faster either.

The TF is just a better casting to start with. Period. The shape of the TF head is far superior to the eddy and you can't fix the Eddie without welding the up. BTDT and it's only worth it if you can't get the TF.

The rocker geometry is much better out of the box with the TF. You may need to make a correction depending on what rocker you have, but it's a small correction. The eddy heads didn't move the shafts near enough for the valve height, and you pay for it with goofy geometry.

If I had a set of TF heads, the first thing I'd do is put them on the bench. Then I'd start looking at important stuff, not just bulk flow. And then, I'd seriously consider a 50 degree valve job for them.

Only seeing one pair of heads and not getting to put them on the flow bench, my first thoughts were these heads would love a 50 degree seat. A few quick tests on the flow bench would answe that either way.

The real issue is two fold. One is where the pushrod is. Guys don't like to say it, but pushrod pinch is bad. It's that simple. So is making the port go from small to large from the intake flange to the bowl. You want the least amount of change of size you can get. With the pushrod where it is, you are going to end up with a bowl that is too big for the runner. It is what it is.

The other issue is the low port angle. Had Chrysler stuck with the W5 and did some minor improvements that head would be selling like hot cakes today. But the short sighted dolts running the show never pushed the stroker guys to get enough head on their big stroke, low Rod ratio engines.

I have no problem telling you to sell the eddy heads and getting the TF's. You'll have a better head hands down.

If you really want to see a performance increase, you need to go to the W2 head.
