My home inspection of Speedmaster heads

I've got a new 100ml burette on order, and I've got one of my bare heads in the car so I can build a stand for the head. Not to deter you, I'd like to know if there's a difference between the cast/ported heads (don't think there will be). Hoping to have numbers this weekend myself.


Sorry for the holdup but if I have to get this figured out. Lord willing maybe we will race sooner or later this year.
