Depends what you want from the combo. Street car or race only? Probably does not really make sense to do it unless you utilize those heads to their full potential. You're not going to see a huge gain over ported heads until you start getting into porting and higher lift cams etc. Whatever combo you come up with is likely gonna make peak power at a higher rpm. What they are is a better starting point. Ported W2s will get you well beyond a ported factory head.
Besides the valve gear, you need specific W2 intake and headers.
I have W2s on my car but I got it with them already installed. It's a milder street combo - MP .557" solid cam, Victor 340 intake, Harland Sharp rockers, TTi 1 7/8 step headers, approx. 3,500 stall, 4.10 gear. Had 4.30s originally. Goes to 7,000 rpm. Probably makes around 400-425 hp. Best time was 11.97 before I got it. Made a lot of changes but mostly chassis. No times after changes yet. Should be faster.
If I do build a different engine for this car at some point I'll probably go with the RHS heads I have or some Edelbrocks and get them done up.
