Knowing your use now I would install and degree that solid roller cam with between 3 to 6 degrees advance on the intake lobes
Be ready for more power than you may want though
Buy the best solid roller lifters (with .820 or larger wheels ) you can get and run at least 250 Lb. on the seats and 600+ lbs. over the nose to help the lifters to live, have the # 4 cam journal groove the width of the oiling passages in your new cam and around .030 to .045 deep this will help the valve springs live in your type of non drag race driving What type rockers and shafts are you using, needle bearings or non needle bearings with extruded aluminum, stainless steel or ductile iron
If needle bearings use a .040 to .065 restrictor in the rocker arm oiling passages, both sides if your using stock type rocker arm oiling, if external oiling like most Indy heads use put that size restrictors in each line to the heads
