ya you should be ok. the gsr head has a smaller Head cc size so it'll raise the compression slightly. depending on what pistons are in the block, a b16 is either 10.2:1 or 10.4:1 Compression Ratio. with the gsr head you'll get 10.5:1 or 10.7:1. that's not including if there was any material taken of the head or the block when it they were rebuilt. with 10 thousands of an inch taken off the head or block your compression ratio could be 10.8-11.0.
