A/C bracket with Edelbrock aluminum heads?
A friend of mine is putting Edelbrock aluminum heads on his '69 400 and the center head bolt bosses are taller than the others so he can't use the stock head bolt with the stud for the rear a/c compressor mount. He has new ARP bolts for the heads which actually have longer bolts for the centers. But of course they don't have the stud for the bracket.
I told him to call Edelbrock Tech Support and see if he can have those bosses machined down. Has anyone else come across this and what was the solution?

Is he able to modify rear compressor bracket instead? I'm not sure what they look like on a '69 without searching.

The '69 A-body bracket attaches to the underside of the head near the valve cover and doesn't use the head bolts. Might be an option.
There's an upper bracket that attaches to the intake manifold and triangulates with the compressor, but I don't use it on my car. Just this bracket and the big cast aluminum to hold the compressor.

Thank you for the replies.
The bracket in question though, is the rear adjustment support as seen in the attached illustration. Not the circled triangle ( hey I "borrowed" the pic from eBay ), but the stamped steel bracket that it attaches to as seen above it to a head stud.

Hmm, I don't have that bracket going to the center head stud with my setup. Maybe it's missing on my car or they added it in later years.

I've been using the '69 iron compressor bracket without the rear support for the past 30 years or so without issue, if that helps your decision. |

Thank you for the replies and photos.
He called Edelbrock and found that the tall bolt bosses were just for looks and he can mill them down. So he took it to a local machine shop to do that to the one boss and installed the bolt w/ stud. Problem solved! Now the next issue are with the Edelbrock intake. Which required a later style offset "Y" bracket for the compressor top rear support which he has acquired. Then there's the choke stove of which he has found an electric divorced choke kit. I just laughed and told him "yeah, the trials and tribulations of aftermarket. I still find it hard to believe you wanted to do this to your otherwise all original Judge".
