I believe that Checkline makes those testers and the PR-8V from Checkine is over 200 bucks cheaper then the sourse stated above.
Joe, with a D port head and a at best .180"wall thickness at your disposal everywhere (assuming no core shift and loss due to rust) , even going for a 88% valve to throat percentage ( 2.11" valve ) and a matching circumference else where, will leave you with.055" thick port walls at best!
That's too thin for my liking on anything else but a race only motor where I can use ciramic sealer to add some reinforcement to the walls.
And yes, it's a pain to post up flownumbers on here if you do already have then on a chart to post up.
