They've been around for awhile, but I've never heard of anyone running them. Or even SEEING a set. They were supposed to make some 429-460 heads too, but that never happened.

there are plenty of great heads out there that are much cheaper so its hard to justify the price of a 32v head.

just for the record, there are other companies that make a hemi head and a head that has no valves for the 5.0

the valveless heads are about $10k a set if memory serves

Wonder how much those heads DO cost?

86 5.0L

In another thread I think they were quoted at 9 or 10k

it would be sweet for an exotic build. can you image a 4.125 bore 427 aluminum dart block stroker with these heads and some weber carbs on top.......

And for the same amount of money you could build a turbo engine with custom efi that puts out 2-3x the power. I wonder how they drive the distributor and how the ohc's are driven as well, if it's a chain drive then the entire front timing assembly would have to be changed(no doubt some custom piece they sell you) and when you start adding in all the extra cost to be able to run those heads you're prolly talking close to 20k for the heads and all the supporting accessories. I mean really, do you just run a cam in the block for the sake of being able to turn the dizzy and oil pump? Or do they recommend you convert to a crank driven oil pump and dry sump lubrication? There's another several thousand. And again, how do you drive the cames for those heads when the Windsor blocks weren't designed for that.

its pushrod, so none of that changes. and who cares if you could build more power going another way. its the unique factor.

if i were at a show and a motor as i rattled off was sitting in a car next to a higher hp twin turbo stang i would be all over the dohc webber setup making sticky in my pants

Pushrod? That's a pretty slick setup, but still quite pricey. It does have the uniqueness factor, but if you're looking to make power there's much better ways to spend money
