So I messured the compression today with a proper compression gauge to see were I'm at and also to make sure there isn't a leak (maybe through one of the new seals or somthing). After a few tests the average grouping was 170psi. I hear normal compression is around 150 so Im guessing 170 is better is towards the higher end. This will be the compression that ill try to obtain again when I grind the head to compinsate for the spacer.
