Highest flowing sbm heads?

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.
Harland sharps on jegs right now 1350
I can definitely see a solid roller spring retainer locator setup costing $1k
Fair on the valves, $800

I don't think Ti is needed at this rpm level

$1200 right now for a pair of new w2 castings

Yeah you got me. That's before port work.
