Are the cam end plugs supposed to stick up past the valve casting surface. I installed mine and they stickpast the valve casting surface by about 1/16". The won't go in any further.

They can stick up a little since the valve cover will smash them down some. If the plugs are old and hard though...all bets are off.Ed
To measure is to know.

They must be brand new ones. If so, they are pretty soft and they'll probably compress enough to be flush with the head's gasket surface when you bolt on the cover.
Last time I adjusted valves, I reused the old end plugs and they still extended above head surface slightly. I used a Realgasket silicone gasket and it would not seal 100% at each end of 3 end plugs where there was a tiny gap. Result: a little seepage. This can be cured with a tiny amount of Ultra Gray sealant applied in the area at each end of the plug where it meets the gasket surface. The object is just to level the gasket surface so that there are no gaps that the gasket can't seal.
I think the Suzuki shop manual mentions this cure.

I couldn't press them in and I would have had to torque down the valve cover real tight for them to seal. I ended up filing the top down a bit and now they fit fine. Thanks for the help.Comment

If they start to leak then buy new ones and put it altogehter in a warm place, those plugs can be a little stiff if it is cold and then they will not compress to flush when the valve cover is put on. Experience for me perhaps?!?!?
