I originally purchased my stuff from Dove.
Then I upgraded to the Precision Oil Pumps set from Doug G., including ends stands and soldi spacers.
This was quite a while ago and at that time his kit was using the ARP studs.
The ARP studs were easy to install and have not given one second of trouble.
The studs do make removal of the rocker shaft a bit tricky because you have to either remove studs, or pull the shaft off basically in perfect alignment...otherwise they are easy to deal with.
