Great
If you're doing this with the cylinder head still on. Make sure you blow everything out before you finish and put the valve cover on. But do not blow air down into the push rod holes. I did on mine. And got lucky. It caused the ungodly lifter tick. Found out which lifter collapsed. Poured oil down the pushrod hole and got lucky in the tick went away

Pretty Sweet Deal
These are easy to swap out in place of the factory springs and seals. These are 560 lift max so be aware when choosing a cam. For the new engine builders do not pick a spring rate too much higher than your current or future planned cam lift specs. Doing so will add undue stress on your valve train.
