So I torn my top end apart last night to test out my new dremel tool on it....The stock jug looked amazing compared to most of the pics I've seen on here! There were no casting burrs on the ports or transfers! The transfer ports were lined up(mapped out on paper), had a good forward angle and the piston opened completely on intake and exhaust ports. All i did was blueprint, or round off all corners, matched header flange and intake tube. The SBP expansion flange was horrible! I roughened up the intake and tube for better atomizing, and sanded jug for a little more compression. I ran it good and hard today, finding little performance increase but low end throttle response was quicker. I worked on the head when I first got the motor. Going over to bro's house tomorrow to use his compression gauge. Hoping for 120-130psi. I'm very pleased with the quality of this motor! Looks like I got a good one!
