That's wrong right there. It covers the Mag ports fine I've used 8 of those in Mag swaps & the only things that I've encountered was excessive casting flash that needs removed to allow it to seal right. After using the first one 7 years ago I look it over for that & grind it off if it has it
Fits only with a RV2 A/C compressor Direct no mods bolt on
Performer RPM is the only thing that really works correctly with A/C & serpentine. It requires mods to use all the correct bracing to keep the big aluminum ones from cracking. Edelbrock also put the heater nipple directly under the A/C pump so you have drill & tap the boss on the opposite side that's cast too small & barely is large enough for the factory fitting to have enough threads
