They do look mighty good. The more the merrier, I say.
That said, I wonder however how well these will sell in today's market as the have lots of competition, especially among the racier LR-MR based heads now available. They will sell as I'll venture they can undercut E-Bock's head a bit. On the race side, a number of shops offer CNC Edel-B porting to the std. and Pro-Port heads already, meaning one can almost design their own custom ports, within the limits of the casting of course. Then one also has the BT heads, Pond's heads, etc. Frankly, the still-born billet FE that was highlighted over on old Forum a few years ago was more exciting as it offered radical changes to just about every aspect of the basic Ford design with CHI/AFD/Cleveland-like intakes, Yates-type tiny combustion chamber, straightened out exhaust port (i.e. #1 and #2 ports no longer angle towards each other) and more.
'Course, just how many radical heads (a wet version of the above or modernized HR/TP heads) could the market support? Not many or not enough to make any volume run or these specialized heads.
