1988 isuzu trooper 2.6l timing issues

I have a 1986 isuzu trooper 2.6l that had what I thought was a leaking head gasket. Upon removal the head was found to be junk. I purchased a remanufactured head including valves and cam. The question I have is how to properly set the timing. According to the haynes manual you line the mark on the timing belt gear on the crank to the mark on the block that is appro. at 12oclock to 1230 position. That should put #4 cyl at tdc. Then line the cam mark on the cam gear with the mark on the cam( 12oclock position) Since the cam turns at half speed of the crank, I would assume that you line the cam up with valves closed on #4 cyl after the intake valve closes? Also would you line up the distributor up to fire on #4 as well? I may have had it out of time the first time I tried to start. Would this bend valves? Need help please!

Yup, if you drop the distributor in with the timing marks lined up, you'll need to drop it in pointing to #4.

I guess you replaced the 2.3 with a 2.6.

If you only had the distributor out of time, you won't have any piston/valve interference.

you need to manually make sure the motor is at tdc with something in the plug hole, etc. don't trust the crank mark, the balancers are notorious for slipping.
