I'm familiar with the AFR 210's, 195s, Edelbrock performer and performer RPMs.
All are good heads.

To get the edelbrock heads to flow near the AFRs they will need porting.
Both edelbrock castings are near identical 170cc intake ports, the RPMs
have stiffer springs for higher RPM.

The AFR 195s are a good choice for a light weight street car or for racing,
not ideal for a 4000 LB truck but will work.

The AFR 210s are a good choice for a race engine, defiantly not for a
4000 LB truck.

So if I were you I'd go all out and get the AFR 180s or save a few bucks
and get the edelbrocks.
