Real data. EQ standard replacement Magnum head and comparisons with oem and NZ versions.

Even with the Edelbrock 360 gasket, the port alignment on the heads isn’t very good.

I’d be curious to know how much different the bolt holes and the bottom of the intake ports are, as measured from the bottom of the head, between those Chinese EQ’s with the LA bolt pattern......compared to an original factory LA 360 head.
