well its not my pic but i just ordered these this morning. already in the mail, and my fuel pressure gauge sold while i was at work so ill be purchasing the head studs later today. with the pistons i selected, compression will be bumped from 9.1:1 to 12.3:1. hopefully not too high to run on pump gas
