Which Valve Is Which

[Scooter]

Hi again,

I need to verify the ignition settings on my engine before startup, and for the sake of my sanity, I need to know for sure which valve is at the forward most position of the Healey straight-six engine. This may be just my lack of keen observation, but when I look at the intake and exhaust manifolds, it isn't clear [to me] which would tie in with which valve.

Thanks,

Scooter

Hi yourself,

The valve layout from front to back should be --
E,I,I,E,E,I,I,E,E,I,I,E.

The valve closest to the front is exhaust, then two intake,2exhaust,2intake,2exhaust,2intake and one exhaust at the back. The valves are "siameesed" to make casting easier.

This is the arrangement for the separate manifold head. I'm uncertain if the head with the integral manifold is the same, but I suspect it is.

Thanks guys, I went home last night and looked at the arrangement again, and it all made more sense.
