Thanks and it does clear the thermostat housing along with the crankcase breather port.
I made a little bit of progess on the prototype manifold
I have started to my own dies to swage the tubing transitions going from the exhaust port to runner primaries. I still need to heat treat them but initial tests show that they are working great! This is a 30° transition taper turned from 4340.
These are the proto mani primary transitions fully welded
I'll have more progress updates posted soon
