Highest flowing sbm heads?

I would expect a set of W2s, fully ported/prepped, with rockers, stands, valves springs etc, to probably run $4k+. That's before the intake and exhaust which obviously come with their own challenges.

I'm sure the porting would be expensive too considering they are iron. No easy path.
Well your wrong as usual......A good set of rockers is 2400, a good set of springs, retainers, locks and spring locaters will be approx 12-1400, valves 6-800 for steel and 1k plus if you want Ti intakes, and are the heads free along with the porting because if so can I get the number for that source as I would like in on this secret. I'm sure your fans will come back with either used parts pricing or cheap junk parts but I don't mess around with used or junk on my stuff.
