Found this in a Facebook group advertised with a 75mm big bore kit (around 271cc, but called a 300).
I’ve asked the guy selling them on Facebook if the 4v head adds to the height or width of the motor but got no useable answer. The 75mm kit with 4v head is advertised for $450, the 75mm kit for $100 shipped.

Anyone know anything about these?

Edit: looks like the whole kit here-75mm and 4v head. Some are claiming it was all installed and dynod at 28 crank horsepower but I haven’t seen any proof of it.
