Bill, thats what I always heard.. But it could be just some type of sealant that was on the big block gaskets..
Brad, I agree with the others, the teflon tape has to go, you don't need it those fitting will seal just fine w/o it. The battery tag needs to go and it also looked to me like there was a GM sticker on the washer bottle.. I would probably take that off also...
Do you have that hard to find and often misplaced little wire bracket on the very far back, left (drivers side) head that holds the oil pressure wire, if the car was non mechanical gauges and electrical?? I could not see from the picture in there but it looked like it was there holding the blue wire....
Like the battery stamps and the original oil dipstick!!
I would wish you good luck but I don't think you will need it.. You will do great!!
