The 4-cylinder stuff has been available for years. You can find it at
http://www.fontana-automotive.com They have a midget engine program and sell parts also. Don't know the $$$'s though. After Joe sold the business he used one of the heads on a stock 153 Chevrolet block in an Opet GT for Bonneville. Did hurt it a few times.
I'm glad to see all the 4 and 6 Cylinder 8 and 12 port stuff coming back and hope it will all works out. All of it will be fun for the street where I believe more will go. Henry Velasco also made crankshafts for the 4. I saw a bunch of them over there a while back.......Good Luck
