My 6.1 retrofit thread
Made some more progress today -
The old and the new.........
The port match between the Modman and the heads appears to be very tidy - from what I could see.
The copper strip is the gasket edge - so there's no apparent lip (on that side of the port at least)
Mocked up the carb etc just for a giggle..........Starting to look like a "real" engine already :p
