It's a Pro Comp Electronics Chinese copy of an Edelbrock head... it has powdered metal seats 9not great for life under hard use & big spring pressures) ultra cheap Pro Comp soft bronze guides....

& then They get CNC'd with a very large Edelbrock port program & it magically becomes an "airwolf" head....

Do they make power? I'm sure they do.... so do really big port Edelbrock heads....

Is the castings & parts of a lesser quality? Yep....

FULLY ported W2 is going to make more power than the CNC Airwolf head.....


According to Dr J's they come with ductile iron seats, and they install their own valve guides.
