Pulled my 360ci SBC from my boat this morning and started tearing it down. Everything went fine as usual until I got to the heads. Removed the 12 pt ARP nuts and washers and started my normal routine to get the head off the block but to no avail. I have ARP headstuds. It seems the studs have seized around the head on the lower boltholes but not the ones under the valvecover. I've used propane to heat the studs and try to get them to spin. This resulted in all but 3 turning freely. I'm very leary of prying as they are good condition AFR 195 aluminum heads. I've never run into anything like this before and am at a loss. Tomorrow i'm going to try acetylene heat on the block where the studs screw into and see if I can get the last ones to spin.
Anyone else ever run into this problem? I've been around and have never seen this before. I'm at a complete loss!
