So for this round, ive been reading around if you have prepped and cleans block and heads, to install the gasket dry from alot of threads and reads. I have copper spray for if I have to ever tear it down and reuse them as many have also mentioned. one of the reasons i got anothet ls9 head gaskets so i didnt uave to clean the forst set, plus i wasnt if there was an issue with those after the LS1 had a head leak as well from the ls9 gaskets before. unlikely but just in case.
