The " calling cam experts " title of this thread is also the answer.
I had an unground lobe billet for my 48 degree heads and called Bullet.
It's been a couple years , but I seem to recall Ken as being the guy I spoke with.
We spent at least 20 minutes on the phone as he interrogated me.......I wanted a lot , as the car would see street duty too.
He asked about head flow numbers , compression , gearing , transmission , car weight etc. etc.
He decided on a 626 lift , 260 & 268 @.050 with a 106 center line.
I degree'd the intake lobe to 102 as recommended and tightened up the lash a tad , it seems to work very well.
Crisp street manners.....instantaneous throttle response and it revs as high as I need it to.
I didn't have the $$ to dyno the motor , but it pulls past 7000.
Even if there were shelf grinds for the 48 degree deals , I would have still called someone in the business and picked their brains.
