Mild home head porting advice .

What kind of advice ?
Work the straight side ssr just off the seat to a more vertical shape than the buldge it is and at the last 1/3 from the top...ever so slightly lay it back and leave a lip, don't round the top of the ssr to the floor, you want a definitive steep ramp.
Thin the guide, shorten its height about 5/16 and grind the guide tail to mimic the set angle.
Open the rest of the bowl , keep it a little smaller than the seat, use the throat cut to guide you and leave an even .100 of throat cut for now, don't grind too much on dogleg side of bowl, go straight up from throat cut on straight side of bowl.

Hard to put it into words, so be conservative. Tall is good, laid back too far is bad that you cannot come back from.
