I just did a compression reading on number 1 and 2 cylinder after I did A complete rebuild top and bottom, bored it .020 over new pistons and everything, and so far I have put on about 80 miles and both readings on the cylinders is about 110 psi? is this common for a rebuild? Thanks.

Did you test like JM suggests?

Might want to look at this link and maybe your numbers will come up a bit. Hope this helps.

Numbers do come up as it breaks in. Mine sits at about 210 about 10k miles after a rebuild. A lot of people get around 140 right after the rebuild.
