I did this just for fun. I was able to find 2 new sleeves but I wanted to see if this could be done and wanted to try a turbo plug head. Someday I will put the right sleeves in.

I finished the car sleeve on my xm Its at 124 transfers and 181 ex I shimmed it with 19mm toyota oil drain washers then raised the ex with a carbide. it was actually at 124 160 stock. So the scanner rc 3 port 21 sleeves work with stock timing for the muffler and I can readily get them if anyone ever wants to do it ..Then I took down the new turbo plug head so I can go as close as 2 thou I have it at 7 to 8 right now for break in . I didn't do any crank timing yet. I want to see what it runs like first. I heated it up then started it and let it run some still really tight. I brazed a brass tube in the primer hole of a shell casing then pinched the end to get the flow I wanted. I need to find more rubber caps like this one I am unsure what its off of .. I melted a hole in the top with a rod to inject oil. The cap acts like a primer bulb when I was done I just pulled the hose and pushed out the unused oil. The blue head is 2 back to back water cooled tops put together.

If you want to stroke it as well, you can swap the crankshaft with one from the CMB outboard engine. Will fit without any mods, and provide 0,6 mm additional stroke.
I really need to find one then . It would make it so I could run a stock uncut head button and get my squish right.also it would allow me to lower the floor on my transfers as well.
 
I found a crankshaft, it is not completely new but it has many gallons left in it.
Will need your address along with an e-mail and a phone number in order to make up the shipping docs.
