In an attempt to avoid lifter/lube problems like these, I plan to groove my lifter bores. This will allow
oil to drip down from above directly onto the cam lobe. Look at the lifter bore grooving tool on page 379 of the Comp Cams catalog(I assume that everyone who has a Cobra also has the latest Comp catalog). Does anyone here have any experience with this modification? Seems like a good idea to me, are there any Cons?
