Factory HEMI Head!
Fine if port injection is part of the plan
I wouldn't do this conversion any other way, which is why it's not going to happen, You might have maybe 20-30 people in the entire country that might have the coin
and the desire to go the distance with it.
If ever a Mopar mill needed a dramatic improvement in head flow, it is the RB eng.
Remember the Newman marketed Covalt 32valve heads? Almost nobody bought
them, yet they could make an easy 800HP w/a fully streetable cam, $10K for the
entire kit. Intake,pushrods, valve covers, fully assembled w/rockers,the works. Yet
crickets, even with guys dropping 60K on mountain motors, they failed to sell.
I read somewhere that Covalt would refuse to even talk about it out of disgust.
