What strokerman said.

I've got the Roush 200's, 64cc chambers, 10:1 with a pop-up piston (KB116) and zero deck.

im pretty sure that the smaller heads have the 58cc chambers and larger ones like the sr and roush have 64cc's. i know all mine did and i had both sr and roush 200 heads on my 402w.

They're just all cast in the same place, hence the problem. You should get 64cc chambers with the 200cc intake runners, but it doesn't hurt to ask him on the phone.
