Didn't know you could get those! Of course spring pressure would have to be "mild" for a 5/16 attach point, but for a cruiser this is the ticket. You could get a DIRT cheap set of roller tips for a Chevy on E-bay I would think. Good info!
Here's another thought, take the $600, add about $150 in pocket change and get a set of EQ mag heads or 1.92 RHS heads. You can even get the RHS heads with the pedistals cast in for LA rocker gear. The flow of either head will SPANK the OEM Mag heads and all of the OEM valve gear will interchange...
