Nice!
Look forward to seeing your progress. I have yet to start mine since Bbk and large head install. A single valve adjustment screw is slowing me down. Stripped old one, new one here this week maybe.

Question is .... Do you now have 4 valves to adjust or do the two fork off into one?
If 4.... Do they send a new valve cradle or cam cradle or what ever they call it?

Yeah, I think I'm gonna ask Syc to do a port and polish on the head before I toss it in..

That is what I was thinking too. No cams listed for 4 valve heads. Looks pretty solid, even without the P&P it would make a significant difference. Better off sending it to Tom, I never trust new head valve seat angles anyway. They tend to toss together parts off an assembly line and ship it. At minimum, a valve lapping should be done.

Oh I see.... 4 valves to adjust but they join to a single rocker. What size cam did you go with.
You are going to have one beast of a gy6 buggy.

I would venture to say all the GY6 cams fit in the 4 valve head. It appears to keep the same geometry as the 2 valve head. They just stuffed 2 more valves in there and added a rocker arm to the original follower.
