I PM'd Thomaspin but he has not had the heads off the V8 so he suggested I post here and....
.... that is a big help knowing a regular c compressor will work when heads are off.. manuals almost make it seem like you MUST have the special compressor ($200 item)... again thanks, sixto. I am hoping it is just the stem seals but want to prepare and test for other problems. Some post here last week the poster had his torn down and someone claimed should have done the leakdown test before teardown so am doing that and the compression test and hopefully have a good handle on what is required before even starting.
