Default Side timing marks won't fully line up. B18C1

Installed my new timing belt but the marks on the side of the cam gears don't fully line up. I spent a good 2 hours trying to align them the crank is set at TDC there is enough slack on the belt and the car starts and runs fine. Vtec hits also the head was milled at some point but i don't think it was enough to affect the timing. The pic is not mine but that's the amout of "offset" between the gears:

Has block been decked, along with a milled head it would not take a lot for the cams gears not to line up.

What HG did you use?

If everything is working, don't try and fix it.

A set of adjustble timing gears would allow you to "tweek" the valve timing if you think you have a problem. 94

OEM honda HG as far as a I know(3 layer)block could have been decked it's hard to track anything that's been done to this car(16 owners). Everything seems great better if anything just wanted a 2nd opnion on it.

Yes, a small amount of head mill is all it takes to throw off these marks. Mine is shaved .010 so I would know. All it takes is roughly .008 off head alone, not including deck for 1 degree diff. Buy adj gears asap to re-zero cams. Its prob running sluggish w/o them
Edit: approximately 2 degree cam timing diff every .008 taken off head-

Nope it's just as strong as before(is that stange ?). But I have S2:T2's ready for install but will be using stock gears im a broke student so i've got to be consirvative where i spend. I'll give my tuner a call tomorrow and ask him.
