Think Padgett's still have 26J and 59W. Sit down before asking how much

I see Fondseca sell TZ pistons on ebay. What about Racing Lines or Dennis Trollope?

flowed the bottom cases, just need to finish it off with some wet and dry. I'll probably get the KR1 barrells ported as they are the best condition of all my cylinders. A question for MJ and the others with tuned engines - approximately what head volume or clearance volume should I be looking to set if I am to run 50/50 avgas?

The values in for the hemi-head sheet are what I am presently using (I run 50/50)
Never measured with liquid and kept results (haven't got the kit to do it accurately). Ignore where it says Piston flat top that is for a dome
Think people say the plug is 2cc so measured to top of the plug hole would be about 10.9cc
