[Fot] I cut intake & exhaust port sections today ( tr4 )

[Jim Gray]

FoT,
I cut some TR4 port sections today, right down the middle of the valve
guides. It sure is a different view of the 

TR4 ports. The exhaust port is a mess. I'm going to try welding around the
back of the valve guide boss

and try to smooth out that wall the exhaust charge slams into just outside
the valve seat.

We'll find out on the flow bench, I have three more cylinders to experiment
with
