Missed on this combo?

Harland Sharp make the least expensive w2 rockers these days at about 1 grand. There are a couple of sets of mp rockers on eBay for 650 with no shafts or stands
Shafts are 150 each..stands are 100 bucks
.and you need New push rods

The HS. are a complete set
.
Man that is expensive for the Harland's
Really would to build a "large headed " 408 but that's tough to get past
