"EQ" Magnum cylinder head differences

Yes I got these heads flowed as I was skeptical on the lack of workmanship. Far from what he's advertising on his website for flow numbers. The exhaust ports are not even touched. Peaks at 150cfm at .400". Intake side peaks at 250cfm at .450" but then gets so turbulent the flow just takes a nose dive to 230cfm at .500".
I'll never deal with PIE again!

NONE of this surprises me. The port is just too small and too fast for the shortside. Even getting a REAL EQ head to flow above .500" is a challenge--these Chinese castings are worse. The good news is 250 cfm @ .450" CAN make a lot of power--like 2.06 hp/cfm if you have a semi-serious shortblock under them. The Magnum head works-you will like. J.Rob
