I hate to break it to you but those rockers are stud mounted, we require pedestal mounted unless the heads can be machined for studs, that I've never heard of being done on our cars. The best bet I have found so far from Jegs/Summit is the Ford Motorsports 429/460 rockers (FMS-M6564C351) that Summit offers in a pedestal mount but they are still about 260$. Though 4 people could get 3 sets and split them, end up about 200$ each.
