** NEW ** Trick Flow LA cylinder heads introduced at SEMA

It won't take much porting if you get the valve job right. You have to buy rockers anyway, unless you already have them.

When you pencil it out, the actual cost isn't much more. There are used intakes for sale.

In the world of standard port height heads, the W-2 would never be obsolete. I've been hearing the cost thing since 1980 or so. The Chevy guys used to ***** (just like the Chrysler guys) about how much the valve gear was going to cost. But just a decade later, the Chevy guys were spending big $$$$$ to get rid of the worthless ball and stud rocker gear. Even on relatively soft cam lobes.

You can't make the power with a head that uses a stock rocker compared to one using an offset intake rocker.

Again, flow numbers shouldn't decide what you buy. The biggest issue getting the W-2 cleaned up port work wise is a quality valve job. And get the chamber blended off. Once you do that, flow the port forward and backward. Then turn the pressure up and do the same tests. Then turn the pressure down and do it again.

Won't take long to see the W-2 is far from obsolete.

All good points, and true.
That said, something like this new trick flow will lkely be able to support as much power as sensibly should be thrown at a decades old stock block. I am talking stroker, compression and roller cam like i plan on
In my case i dont want a 9 sec motor to put in my 3300 pound car. Been there done that. Dont want to fool with all the gear, licensing, and cage that entails.
I can go 10.20’s or 30’s( hopefully) with these new heads and likely wont feel much difference from the 9.80’s my old combo ran with an X block in the seat of the pants.
Few guys are building stuff that runs 9’s or quicker N/A. For the vast majority, my guess is this trickflow will be good enough to push a stock block and run 9’s capable ET’s in a lighter type drag cars.
Hard to say until we see these new offerings, but cant wait to try them
