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

After way more work than a 5 minute bowl blend the intake port is better than the factory magnum head, but not as good as the ootb NZ EQ heads.
Based on what he did vs what they flowed at that point, I’d say a 5 min bowl blend would probably get you pretty close to what a factory head flows.

Interesting situation with the LA version intake gasket fitment.
Although I don’t think he head a proper LA 360 sized gasket to test fit on the head.

Those new EQ heads are not what I’d be looking at for a real “performance” application.
