Used Diamond W2 Aluminum Heads Yay or Nay?

The clutch I've been looking at after talking to Ram and Mcloed is Rams 10.5 twin disc. Supposedly that's their suggestion for the best compromise between street and strip. It's like 1500 bucks for the clutch and flywheel combo. Still researching clutch options though but I'm certainly not afraid to spend the money on quality. Already destroyed the centerforce dual friction so not wanting a repeat of that.

As for those w2's they'd be going on my 408 stroker so I'd imagine those big ports would be ok due to my engines size?

What are the advantages of milling off the 4150 flange on the strip dominator and welding a dominator flange on it? I had originally hoped i could use a Holley 850 dp that I've got sitting on a shelf.

If I get the w2's it comes with TTI 1 7/8 ceramic coated headers and a ported matched strip dominator intake.

Here's pictures of the rockers and intake. Oh and question, what are the two petcocks on the back of the intake for?

BTW, nothing wrong with the parts in the pictures. Intake probably needs some welding for it to be correct. I'm not a fan of 4500 to 4150 adapters. I can make a 4500 plate and weld it on that intake and not have a spacer on it. I have that intake, and that's how I'm going to do mine. The rockers are damn good units. Nothing wrong with those.
