What oil's for flat tappet, stock LA Cams ?

I don't know I like using the VR1 that's made for flat tappet hi performance engines. What's regular good name brand oil a quart $3 vs VR1 at $5 or $6? I'll spend the extra $10/$15 dollars on my expensive engine! No need to pinch penny's here LOL.
P.S. VR1 has usually gone on sale every April or May
