Have you tried calling RHS to check the #'s ? they might be a good and they might not. The smaller runner heads don't flow much according to their own flow charts, how ever the 235 runners flow up to 315 CFM. A good running 383 will need 300 CFM or more to perform at it's best. i've heard those words before they flow like crazy, but unless you can get some actual flow #'s i'd be careful of the purchase.
