question on W2 heads

Yes. Though the standard header port shape is a disastrous mismatch, you could do worse than the adapter plate set up and standard port header. It’s that the exhaust does not care how it gets out vs the intake charge getting in.

Do you have the adapter plate for standard headers?

The W2 headers also come in standard bolt width (narrow) and wide for the bigger tubes.
Like an idiot I sold my old set of Tubular Automotive headers with the plates for standard and W2 heads a few years ago and now wish I hadn't , I have the junk TTIS on my Indy heads in the car now with no plates, I am mainly wondering if I can use regular head headers on the W2 heads just for the dyno. And thanks for the replies!
