45 degree angle enough on the inlet of the bores Bruce? (Was having some fun
with my V8 TB a few nights ago...still have metal flakes in my nose from that
experience. ;) (Now I know why I don't miss porting stuff anymore!) hehehehe

One word of caution on the shaft screws...be VERY careful when you remove
them. A buddy of mine tried to remove them and wound up giving it to me
to "fix". (I sent it to someone who has experience with
fixing "oopsies"...Thank You Frank if you're reading this.) If you start
turning the screws (after grinding off the ends) and they're really tight, do
NOT force them out...be gentle with them. You will break the screws if you try
to force them out.)
