Nice looking head. Appears to be a different casting than the Speedmaster.

Is that a TF twisted wedge head? Is so, do that thing was horrible. It took a bunch of work just to get it decent.

The first set I did was right after I got my flow bench. I fixed them and all the rail birds were sure I butchered them.

Couldn’t get him to go to the dyno by he picked up 3 tenths.

IIRC that was the head was had an 18 degree angle on the intake valve and 23 on the exhaust.

They didn’t do well because they just weren’t that good.

Yeah, they blew elephant chunks, but that doesn't mean the idea couldn't work.

You can make them work. The issue was guys were pissed they bought a head and then had to fix it. They could have started with a better head and not had to pay to had them fixed.
 
just saw this thread, if they're going clean slate, I'd look at doing a big port/big valve polysphere head, since that's what the lifter angle was designed for....

That's what I said. DO I need to tell your wife to hit you again?
 
I wish Blueprint nothing but success in their cost cutting endeavor but there is absolutely nothing “clean slate” about this. Edelbrock copy with Chevy rocker gear.

Does Promax do mopar heads anymore? I feel like I reached out to them a few times and they did not. But maybe they brought them back?

I just talked to them at PRI yesterday. They had both big and small block mopar heads on display and said they are available.

Yeah, I ended up stopping and talking with them too. They had an aluminum gm block also. 6000-7000 is what their ballpark was on that. Wow....
