Hydraulic Roller Lifters w/LA Block?

Hey Sledger, how do you like your roller lifter setup? Is it worth the hassle in your opinion?

You have good dimensions right there on the Hughes page; I would be measuring them all. How much valve lift do you have, BTW? How many bores have the issue? Just wondering if welding up or sleeving 1 or 2 and reboring them would be less expensive.

Cam lift: .541/.537
Full specs: 20-812-9

I stopped by the shop again today and we went over each lifter one-by-one: Only two lifters fit OK and the rest either have an obvious gap or are sketchy-close. The largest gap is the one in the photo I posted above and is a few thousandths of an inch.

If the lobes heel areas are not being ground any lower than the original cam core casting marks, I am not sure how the support is being compromised/reduced? The strength of the cam is the smallest diameter portion .... ???? 'course there could be a limit with the roller diameter that I am not aware if.

This is essentially the same logic that my engine builder was using when explaining to me why grinding is prob going to be our best option. When you consider that the core of the camshaft is smaller in diameter than the lower cam lobe, then having the cam lobe shaved down a few thousandths of an inch won't have any real impact on the strength or support of the cam; especially since I won't be running super-crazy springs or anything.
