Hi, this is my first time posting on this site, so i hope i put this in the right spot. I'm currently rebuilding a 67 chevelle that came with a 350 that apparently ran. Eventually, im planning of doing a LS swap but to keep the budget lower, i want to run the 350 for a couple of years. I did a compression test on all cylinders and i am getting 170 psi on all of them. So i opened it up to inspect pistons/cylinder walls and was going to put new seals/gaskets. Everything looks fine exept for my #3 wall which has a bunch of small scores that run almost the whole lenght of the cyl. My nail catches on a bunch of those marks near the top. Since it has good compression, would it be worth replacing all gaskets and putting this back together, since i dont want to invest much in this engine? Thanks for reading.
