I cant get the lower bolt on the right (passenger) side off at all, i've already broken 2 3/8" drives. is there ANY way i can get it off? heating it? anything? or should i just take it to a shop? thanks!!!
spray it with some PB Blaster or some other penetrating oil ...and let it sit for a while ...do it several times if you have to ...it worked for me on original manifold bolts on my '71

PJ1 makes some great penetrating lubricants that I have used on stubborn aluminum motorcycle applications. I would not recommend heat, due to the expansive qualities existing in the manifold already--you will only treat it as normal expansion.
only two things you can do... 1. is too try and let it soak in pb... the other is too go out and buy a MAPP gas torch.. .you may have a hard time tring too get it in there too heat the bolt but thats your only option without a real torch set
