Bracket Mounting - Non-Acces. Heads

Hi all, Im having trouble finding the correct accessory brackets for my heads.

Car is a 1980 Camaro Z28. Engine is a Chevy 350 with non-accessory heads. Belt driven fan, alternator, power steering. Long water pump. No A/C

As you can see in the pictures, the lack of accessory holes in the heads is causing my alternator and power steering pump to mount at an angle. Obvously this is causing the belts to wear un-evenly, and fly off while im driving from time to time.

So, can anyone point me in the right direction for a low-cost solution? Ive looked around and cant find proper accessory brackets.

Also, i have a tap and die set. Can i drill and tap my own holes? If so, I wound need info on the correct place to drill.

Thanks.

so ive been doin more research, and apparently they are camel hump heads(never heard of them before). I looked at Alan Grove's web site, and found what i needed. However, i dont wanna drop like $200/w shipping on 2 brackets.

If anybody has links they could post me for a cheaper solution(unfinished metal, summit products) that would be great. Thanks again.

Look here : www.alangrovecomponents.com
Whoops, you've already looked there, but they are very solid pieces.
Maybe get inspired and make your own, I have quite often, I'm a fan of the mid mount style alternator brackets

if you have your old brackets just just try drilling and tapping your heads. i had to to that on my engine for my serp system to work although i only had one hole to deal with.

Got me a Z28 with no accessory holes too...

I am not sure if you are using a serpentine belt or v belt, but I have used additional brackets with the original brackets one to mount to the header like you and the other side of the bracket I extended to the first intake manifold bolt and used a spacer to flush height. The alternator I believe I used the intake manifold bolt flush to the bracket and the water pump. I am putting my motor back together this weekend and will have some pics early week to verify, but I have never broke a belt (v belt) but I use pretty heavy duty belts. Previously I was running close to 350hp soon to be closer to 500.

As everyone said youll have to shell out or make your own brackets, which isnt hard.

As the proud owner of an 80 z/28 with a soon-to-be fully forged roller 417, I said buy some real nice aftermarket heads with the holes and then rip on er

DO NOT attempt to drill and tap the heads for mounting. That is the quickest way to render those heads worthless. Yes some people have gotten away with it, but more heads have been ruined than not. The material thickness of those older heads varied dramatically.

Another tip, Heads with no Accy. holes are setup to use a short water pump. That may be some of your problem.
