im just curious, i forgot what people told me what compression i was going to run. i have a b18b with stock rods, stock head gasket, the head or deck has not been milled. and i threw a set of PR3 B16 pistons in there. what comp. should i be at.

oh and i have 2 miles on my newly built motor, and i comp. tested it and it ran 240 across the board. should the numbers go up after its broken in? how much higher should it go up? thanks
