<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Consolas">A while back, Dave McLain flowed a set of old iron closed chamber 4V heads with the 1970's Pro Stock style high port exhaust plate and shear vanes screwed into the intake port floors. I thought I'd share the results. Flowed on a Super Flow bench. Tested at 10" and converted to 28". 2.19" intake valve and 1.71" exhaust. Completely stock combustion chambers.</FONT></SPAN></P>
