Ma suggested the P2806077 spring. for height I'd mockup & see if you have at least .060" clearance between the coils before coil bind. 312/312 adv dur. 104 overlap. 106 cl and 28/32 on the lash but reportedly going less is beneficial. 3400-6900 basic RPM range. drag super comp. 590/590" lift
IMO....... The 077 spring is one of the worst springs ever.
Not enough seat pressure, way too much open pressure.
I actually refuse to put them on customers heads when they have shown up with them.
The 590 cam works well with 145-165 on the seat, 375-425 open, depending on what rocker ratio you'll be running and how high you plan to rev it.
For 1.5 rockers and 7000-ish rpm the Isky 8005-a installed at 1.860 is a good choice.

The Isky 8005 A is the spring I use with them like Mr Porter said.
It also likes to be advanced a couple degrees if you have the PTV clearance.
