I'm removing the dealer installed air off of my 67/ 400. There's a big ugly bracket on the front passenger side, and it's held on with two head bolts. Can I simply remove them and replace them?
The bolts are definitely longer, so I would need to compensate for that. My fear is interfering with the torque. I'll take a picture and post it.Do you know if they used longer bolts? I'm no expert but I'd play it safe and deduct the thickness of the ugly bracket from the threads with shorter head bolts if the others are shorter.

Yes... but doesn't a typical stud bolt have the accessory mounted "on the stud", not beneath the bolt? I want that bracket off, and my question is, can I just remove those bolts and replace them with the correct ones, or will that screw up the head gasket seal?OMT is right that is a stud bolt
The same type bracket but I can't recall if my head bolts are exactly like yours. I'll check when I get home. I doubt you could do one at a time as suggested as you need to get the bracket out of the way first. I'm personally the guy who would just pull them and torque the rear one first then the front.Is yours mounted the same way?
Thanks! I'll keep you posted. Where is the foundry mark? And what will it tell me?Hello
those look to be correct 67 68 ac head bolts ,,,, seen em with and without the stud on top .. 67 n early on the 68's mostly with the stud
just had 2 later a march and april 68 ac cars and they were studless..
if you need a pair of originals non ac head bolts I can mail you a pair ,,, for deleting the bracket ...
what is the foundry mark on the top of your smooth heads... is it a sunburst pattern or a bullseye ??
What kind of engineer? My training was in electronic engineering, and I worked in the computer field for 45 years.Thanks for all of the input, everyone. 35 years later... I've done it all, but I never really got into engine internals (I'm more of an engineer), hence my concerns about the cam and head bolts. The original owner did say that the AC was dealer installed, using the factory AC bracketry, but I can't verify that. I'll first attempt to get the engine builder to do it for me... but he's not answering the phone or returning calls, so he's either very busy, or bathing in corona-bucks and not wanting to work.
Yeah, me too. Which is why the bracket has to go!I’m kind of anal about that sort of thing.
Mostly CAD and Digital Imaging. A lot of mechanical and structural, even some electrical. Currently, I still do digital imaging for a luxury yacht manufacturer. I shoot the boats with a 3D laser and/ or use crime scene analysis software, to produce cad files of marine parts. I'd rather make GTO parts!What kind of engineer?
