Need some advice on some cylinder head gaskets

Thanks turbovan! If that’s correct, he’s in deep doo doo at 10.5:1 and the spacer even with an extra thick gasket is only going to drop it to around 9.5:1. On the spacers, that’s correct. Put the coppercote on the copper coat on the deck spacer and put the SDs on dry with the neoprene facing up. But you really need to find out where your pistons are at. If you’ve got zero deck, you need some super thick cometics.
