    Need help adjusting my valve clearance

    I've got everything in order except the reverse-flow design confused the hell out of me. Which is the intake valve and which one is the exhaust?



    I know the far ends are intake (or at least I thought it is), but the middle 4 valves? halp!?

    Can you peek under at the shape of the intake/exhaust, and determine from there? I seem to remember some of those engines had siamesed exhaust ports, which would mean the 2nd and 3rd from each end would be exhaust.

    Sweet thanks!

    Well, I've decided to put everything back together since I couldn't break the retaining nut free haha. At least not now since I've hurt my back again and it ain't fun.
