291 heads (camelhumps) do not have accessory holes in the ends of them. I have a pair myself that I'm trying to decide whether to keep or not because of that fact.
I've been told NOT to drill them, but it's been done before. I suppose a knowledgable shop could do it but I wouldn't take the chance. I've already decided to dump them and go with Vortec heads.
Hope this helps...
Does anyone have any digital pictures of their original set up? All I have is the 68 Camaro Assembly manual, which isn't totally explicit with details. I have the 7 "major" brackets for the compressor, but in the manual they have a few diferent set ups depending which packages you ordered (L34-35??, manual trans, auto trans). I'm going to have a 327/275hp 4-speed with no smog pump. I'll try to get a picture of all the brackets up here soon, but I was hoping a real pictured set up like mine would help me out.
