Thanks Russ but I'll do my own flow bench work. If we didn't reinvent the
wheel we would all still be running around with wooden spokes.

Jim,
I believe there were a few different castings and among them was a variation
in thicknesses. I ran into this on Spitfire heads also. I had done what you
are suggesting and had what I thought was accurate information on how I
could mill and port the head. I ruined a head right off the bat due to a
casting variation. I found there wasn't a lot of consistency through
production runs.
You might want to check with Tony Drews. I believe he and Jack had done all
this and come up with the hot ticket. No point trying to reinvent the wheel
if it's already done.

Greetings FoT
As the subject line suggests I'm looking for an unserviceable hi port tr4
head. Were going to be doing
some flow bench work in the coming months and would like to cut some cross
sections of the ports
for development purposes. Of coarse we will share the data we gather from
the flowbench.
Thanks for any leads,
jim g.
