I guess my point here if there was alternative B1 (bore centerline valve reliefs) Piston readily available, other head MFG's could develop a head with the superior B1/W8 type Valve arrangement that wouldn't cost much more than the present offererings. If they assumed anybody buying that head was building a stroker, (How many people build stock 3.75" stoke 440 motors out their Keleno, MP or World blocks after all ?), it seems like this wouldn't be hard to do.

As for the B1 header, yes it is an added expense, but maybe Koffel could run a test set of EZ-B1's (sorry indy ) that have a conventionally sized (but still very good) exhaust port.

People say, well it's not gonna happen....and maybe not...but now Edelbrock is coming out with a Victor small block head that has a 2.15" intake valve....so that's not gonna just bolt on to most existing shortblocks without a piston swap (or some serious flycutting mods and maybe upsetting the bobweight/balance)either

What if Koffell, Indy, Eddie or whoever gave Us a BBM head which combined max wedge ports (standard intakes will fit ) BUT also gave us a W / B1 style valve arrangement that opened on the bore center and a more favorable for flow Valve angle?
