I get the point in general, what’s being mentioned are valid, but Johnny laid out parameters. It’s clear to me they want to build their own heads for the engines they offer, up to 500hp, for the blocks that are available.
AND:
Get some input and possibly incorporate as much as possible and profitable into the design so as to be marketable as stand alone offerings down the road.
IMO, IMO, based on what I’ve seen on this forum over the years the engine builders and more serious higher horsepower racers are a very small percentage here. And they are not going to buy a fully assembled anything from Blueprint. At the most a bare head. And since it’s stud mount highly unlikely at that. But they have valid thoughts/opinions.
