Does anyone have any experience with heads for an EVO from a company called Hemi Design? I'm wondering if Branch heads wit JE pistons is the way to go or if these Hemi heads with their pistons are better? Any thoughts?
I read a tech article some time back in American Iron magazine from Donny Peterson where he said Hemi style combustion chambers are inefficient for combustion...to make good compression you need domed pistons and they are no good for flame travel.
