W5 head oiling questions.

the 8043 lifters can uncover the oil band at full lift and cause oil loss. our lifters will not and we do offer them with an offset pushrod seat for the intakes to help straighten out the pushrod. see them here MRLPERFORMANCE.com

I ran the 8043 lifters in a stock unbushed block with a .665 lift cam. With no problems.
