I have a K20 Darton Sleeved Block with 87mm Wiseco pistons 11.7:1. One of the pistons bite the dust and the block needs to be bored .5 to 1mm in order to get it ready again. I found a good deal in some Supertech 87.5mm 12.5:1 K24 spec pistons. Reading some info I found that the compression will drop if I use K24 specs pistons in a K20 block due to the shorter stroke, if so, how much compresion drop I can expect? And also, I want to know if Im going to run in some Valve to Piston clearance problem using the k20 head with those k24 Spec Pistons.
Thanks
