does anyone know the torque specs for a JDM st185?

and when buying the head gasket what thinckness should i buy? 8.8mm or 8.38mm

215ft/lb torque and go for the thicker head gasket to lower compression and make higher boost levels safer

8.8mm?? What the heck. You would have a CR of like 2:1. HKS makes a very good metal HG in 1.1 and 1.6 mm sizes. Don't know about no 8mm though confused.gif
