Im looking through the fsm and either im blind or there is no head cylinder torque specs for the 20. Im planning on doing some head work soon but can't find the torque specs for head bolts and cam caps. Are they the same as the 25?

They are in there, you just have to look. I dont remember what they are but my dohc ka need 5-8ish ft-lbs for the cam caps, and on my RB20 i used 90ft-lbs because I had ARP head studs.
