Congrats on finding a set of 48s, I heard they were NLA.
I'm not a fan of the Spec 10. That's how DHLA 45s were/are supplied by DBE, etc. and I find they are WAY too rich. In chasing the right jettings for my 2.0 and 2.2 engines with an EGT and O2 sensor, I find Spec 9 a MUCH better starting point.
Can I tell you the story of me 'fogging' mosquitos down the back stretch of Roebling Road at 110mph with those Spec 10 160 mains???
Similar to Spec 9, I'm running 55 idle, 135-138mains, 170-180A/C with 11:1 on my 2.2 w/ .388" lift in/ex, 36mm chokes, mild port-matching.
