Why not have the machine shop that is sleeving your block check it all out, and buy some custom length rods to get the required deck height and compression with a normal head gasket? Many people go the other way, and use a shelf H22 rod, and custom pistons to get the stroke from the 95mm crank while moving the wrist pin height to keep the pistons in the block.

already got the h23 eagle rod : and darton sleeves. The problem is that i need those item for my friend who lives in Dubai . since the custom made piston will take 4 week and i cant wait . the supplier here told me to get h22 piston 11:5:1 comp which will make 13:08 comp n h23 vtec. so to make it 12:3 i will need a 1.3mm gasket
