Slant vs. Straight Plug Motors

I have two new motors that I have cleaned up the ports and lapped the heads and barrel. One motor is a RAW brand and the other is a Slant Head from Zoom. If you look closely you will notice the intake port is larger on the one to the right. Also notice the design of the combustion area on the heads. Like I have said before...I have experienced more overall performance with….guess which one…


I will also post some pictures of the piston skirts which are different.
