I just ordered a custom set of Johnson lifters through Scorpion. Johnson is a supplier for Scorpion and has a real good rep for quality. Plus they're built in the USA. They may be Johnsons...if so, I would use them.
The reason I went with Johnson is because my 2000 mile motor is apart because of a failed Comp lifter. They are twice the price but worth it IMO. I could not find any bad reviews of Johnson lifters.
I spoke to Jason at Johnson and he was very knowledgeable and helpful as was the guy at Scorpion.
