Does anyone know what the part number for the two sealing washers that helps seal the crossover tube to the back of the heads? Or where to pick them up? I haven't called GM and I figured that was something a local parts store would have. I may end up using the ones that fit on the ac compressor if I can't find anything. Thanks

i would like to know this too, i never asked the dealer and i ended up using oil drain plug gaskets...

Probably should change the bolts too PN#12552974. The early 93s had some odd sized heads, metric was too big and standard too small, and stripped easy, the replacements ( I think ) are 13mm.

I paid around $20 for 4 washers ( two each head ) and the bolts.

Cool, thanks for the info. I called the local dealership. They had them in stock and were a little over 7.00 a piece.
