Oil From the Exhaust Ports?

I'm beginning to feel like I might have bitten off more than I can chew.
I bought a '63 CA77 knowing nothing about mechanics or motorcycles. I read what I could, bought my Bill Silver guides, spent a LOT of time prowling these boards. I got it running but blew a head gasket. Had the cylinders honed and the valves lapped. Pulled the entire engine, went through it completely. Cleaned out all the gunk - and there was a LOT of gunk. Bought and installed an entire new top end gasket set from Western Hills Honda.
I followed Silver's guide to the letter and felt confident that I'd installed the valves correctly- the timing chain was straight and true, the punch mark was at 12:00. I set the valve adjustment to .005 and torqued the valve head cover down in a cross pattern to 15 ft lbs.

SO: I finally get the engine started after fussing around with some electrical snafus and it purrs! Of course, the throttle is sticking and the clutch is almost completely worthless- if I pull it in it still doesn't disengage, but I'll get to that later.
But it's running and it sounds great, even with one muffler disconnected. I'm thrilled for about 3 seconds until oil starts SPEWING out of the exhaust ports.

I found another thread that sounds like a similar experience, but it seems to have dropped off and was never answered.

Can ANYONE point me in the right direction? As always, I appreciate anyone taking the time to help. I'm enjoying the learning process but sometimes my inexperience frustrates me and I'm going on 2 years now without a single ride!

What do you mean by exhaust ports? Is the oil coming out of the mufflers or is it leaking out near the head where the pipes connect?

[houseowax]

At the point where the headers connect. And it's really flowing out of there.

Hmmm.....exhaust valve guides ?????

Yeah, but what exactly? Like I said, I had them lapped and I tested them for leaks before assembling the head.

Your valve faces could be good and sealing but you may be getting oil leaking down past the valve guides. I can't imagine that would be spewing oil though.

Are the O'rings installed correctly around the alignment tubes between the cylinders and the cylinder head? On my bike the P.O. did not install them and I had a serious oil leak from the front of the engine just under the exhaust connections.
