Finally got my engine together this weekend.
b16 head on a b18c block, using a mugen head gasket, stock cam gears.

The problem is that I set the cam timing and everything lined up good. When i started the car it started up every time, however the car wouldn't rev over 2500.

I checked the ignition timing and it was way off. I moved the distributor all the way towards the firewall and it got it closer but it still is quite a bit off (the white line is lining up with the mark on the cover). I know that the mark on the cover is supposed to line up with the three other marks.
when i did move the distributor all the way forward the car would rev better(wouldnt stutter).

my guess is that the timing is off a tooth, the only problem with this theory is that when its all put together the cam marks line up and the crank mark seems to be dead on.

Is the mugen head gasket messing up the timing?

codes that I have are 8 and 20. would this affect my situation?
When i set the timing I made sure the cam sprocket marks line up. and the mark on the crankshaft sprocket lined up to the mark on the oil pump. When i put the timing belt cover on the white mark does line up with the timing belt cover mark.

now when i start the car it starts and idles fine. It is very hesitant to rev( plus i dont want to mess anything up so ive only revved it up a few times to 3000 max)

to check ignition timing, I let the car warm up to operating temperature, jumped the diagnostic connector with a wire spliced on each end, and got the idle down to 750rpm. when i checked the timing with the timing gun it intially showed the white mark lining up with the mark on the timing belt cover.

I advanced the distributor all the way and checked the timing again, it was better but not nearly close enough, the mark is about halfway between the white mark and the other three marks. so basically it is running very retarted.

 

Im running buddy club spec3+'s if that matters

 

I dont know about your particular head swap but I did a sohc 1.5 block with 1.6z6 head and the head was milled to a different height and I had the same problem I installed an adjustable cam too make up for the ,head height - (witch is basically puting u half a tooth or so off on your cam gears while your marks still line up) so I installed the gear and tuned it in and it worked great. that is prob your problem.

 

I actually had two wires switched at the distributor, after i fixed that i was able to set the timing correctly, The car now runs ok but i need to get cam gears i think to make it run to its full potential.
