Keep the tail long, have some 1 pc bronze put in. Stick to a 3 angle vj, no 15 top.
Blend all around the intake valve in the chamber, a little into the chamber on straight shot, open pinch to max .050 thick or a hair less. Work the roof a ton and smooth n ramp it down keep the throat on the small side till the vj is done, make the bowl almost a bell, do not over work the straigh/common side ssr...and almost leave the dogleg side of ssr tall as you can. Work on cross section but keep rounded/bullnosed. Common wall straighten to head bolt but dont make it flat all the way into the bowl, let it still kick out..so that there IS still a bowl on that side. You want to feel sharp angles at seat but also radius that throat from them. Dont make a bucket out of it.
Only knock some of the wall to floor hump down, for area at the ssr
