ok my girl just blew her timing belt on her dc and so i took the head off and it bent a few valves. well i checked on craigslist and found a used one that was in good shape for cheap. there is a problem it was missing a few cam caps. so what i did was take and put mine from the other head one and the cams would now not move so i went threw and found which ones were dragging and changed them out now the cams move nice( i took the cam tappets out for this part) i was wondering what the final torque is for the cam cap bolts? and what is the torque for the head bolts. please any help on this topic would be great.
thanks

These specs are for a B18A, so your specs should be the same:
The cam caps are only torqued to 7 lb/ft, that is not much torque at all, just like the valve cover bolts.
The head bolts should be torqued in proper sequence, starting in the middle and alternating up and down towards the outside. Begin with just seating the bolts, then 20 lb/ft, then 40 lb/ft, then 61 lb/ft as the final torque.
You probably would have been better off just replacing the bent valves on your original head because the cam caps are specific to each head. Your probably just fine tho. Guess you could use plasti-gauge to check the cam cap clearances.
The cam cap are numbered and marked intake and exhaust should not be swaped around in the head.
And it is a big no no to change them from one head to another. They are machined for just one head and to go in just one place in that head.
Not say that you can not get away doing what you did. Make sure you check everything.
I have heard not to do it but i got a real good deal on the head and figured that if at anything i cold have it line honed but i am going to plastie gauge all the cam caps to see if i have a big differance between them.
thanks for the info guys

ok i just did a valve job on the other head and took off the valve seals to just make sure everything is good. my question is what is the best way to put the new valve seals on?
thanks

I used a small size socket connected to an extension and then gently tapped them in with a hammer. make sure the socket you choose isn’t so small that it messes up the rubber or spring
