This is what I've done to mine. I raised the exhaust 2-3 degrees to increase blowdown and opened the exit. Widened the transfer and blended the plate that sticks into the transfer. I opened and squared the intake and lowered it 2 degrees. I didn't touch the stratos as they are restricted by the tiny square holes in the intake manifold. I also raised the lower transfer opening. I cutout the strato part if the piston when it is at tdc to not restrict the flow.
