Default 94 Prelude, crank and cam bolts torque spec needed

I purchased a '94 Prelude Si, twin cam (125k miles) on Tuesday and am in the process of changing out the timing belt/wp and seals and need the torque numbers for the harmonic balancer and cam fasteners. I borrowed a 600 ft lb torque wrench from work so that part is covered. In addition to the timing belt I'm also rebuilding the a/c system with a system flush and new condenser and compressor. The oil in the compressor was full of metal. The evaporator is on the workbench getting a good cleaning. While I am at it I'm replacing the sunroof exterior panel and seal too. The panel had a couple small but severe rust spots.

I think the 4th generation Preludes are one of the best looking cars ever built. I'm doing all the work myself and going with original Honda parts with the exception of the a/c components. The majority of my mechanic experience up to now has been on early 80's Mercedes Benz diesels.

I did find the timing belt sprocket split along the keyway when I took everything apart . Seems somebody may have missed the mark torquing it down at one time. I may heat the sprockets up to make it easier to install them. Any thoughts along this line will be appreciated.

iirc cam plate bolts are 19ftlbs for the 12mm and 7 or 8 for the 10mm bolts.

i cant remember off the top of my head but thats pretty damn close if not right.

for the crank, just get it as tight as possible with a breaker bar. It will tighten itself even more once you start the motor.
