Looks like I might get the e-streets and the thinnest gasket. I haven’t pulled the heads and measured deck height but I used .140 and hoping it’s better than that. 8.8:1 is what I got in a calculator based off 75cc head, .027 gasket, and .140 in the hole piston.
I forgot to mention I have power brakes so I think that rules out the whiplash from what I’ve read. Also, 91 is the highest octane anywhere close. I still would rather not change out the converter and gears.
