i'm planning to get a new cometic head gasket for my h22a1 motor but i'm not sure what thickness i should get. i know there is a lot of post out there about this but i need help specifically for my setup. here is my setup:

both h22a1 block and head
89mm, 12.0:1 cr wiseco piston (benson sleeves)
h23 crankshaft w/ h23 crower maxi-light rods
skunk2 stage 2 pro series camshaft
skunk2 hich comp valves

 

Figure out what clearance you need, do the math, and order a gasket.

I hope by now you know that the cr given by the piston manufacturer is specific to a certain engine setup, and they most likely didn't use an 89mm h23 vtec when they gave that spec.

Do the math.
