Since oil and lubricants has been a huge topic of discussion over the years, I think this is an interesting article on synthetic motor oil.

On a 20/22 can a camshaft be replaced without removing the head and installing a new head gasket: FACT or MYTH?

I found this nearly 15-year old short thread on replacing a camshaft and it is interesting that it seems to be a common misbelief that you cannot swap a camshaft in a 22 without replacing the head gasket.

Read post #5

Swapping camshafts on race engines is done all the time without removing the head.

If you are rebuilding and engine and you have ANY idea that you might swap a camshaft in the future, or have to replace the rocker rack, install an ARP Stud Kit and then you will make a future swap easily and with less risk of causing a problem with the seal of the head gasket.
