** NEW ** Trick Flow LA cylinder heads introduced at SEMA
2200.00 looks pretty good to me. Looked into W2s total conversion with porting was going to be 5000.00 plus. Rocker arms are crazy high for these things.
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.
