Edelbrock Air Gap
I just had mine ported, and the porter cut .020 out of mine. I didn't know he was going to. He did all the R&D on the P6 and P7 heads for Penske racing, and ported all their heads that won a NASCAR Championship, so I'm betting he had a reason, and not complaining.
I have run this intake with and without a 1" spacer, and couldn't feel a difference on the street.
The only time I ran the spacer at the track I was having unrelated fuel starvation issues, so no good data to compare.
