Manifold looks mint javier.excellent work.does that gtir prototype clear thermostat housing?
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.
