I have a H22 block that is missing a piston and rod and the cylinder walls are a little scratched. I was going to bore it out but my friend who is helping me said he was told I couldn't. He said I could not punch the sleeves because they are floating sleeves.So should i just buy a new block? If so, then I am looking to buy a h22a1 block and I am also looking for the internals (stock or performance). Any help or deals is greatly appreciated!
