Then I saw this:
http://boatheaders.com/reversion.htm
Where Lightning headers recommends them to reduce reversion. I was sold at that time, although I would like the rough idle sound.
Note that the info in the webpages is outdated, the Rhoads Lifters are now available as rollers.

Unfortunately I do not see them listed for a GM 496. The 454/502 lifter will not work because of the different oil galley in the 496. I think Crane and Morel are the only sources for the 496 lifter other than GM and the Morel is only good for the stock lift.

I am still sorting out some issues w/water in crankcase, but hopefully I 'll be running this weekend. I'll let you know how they work on the water.

I just talked to Rhodes. No they do not offer a V-max lifter for the 496 but.... they will convert your existing 496 lifters to the V-max for $95. There is some question as to if the current push rod length will still work.
I asked about noise and was told it was "not too bad" and goes away above 4000 rpm. Reportedly this lifter design has been around since the 60's.
Why has this reversion solution not taken the high performance NA marine applicatiopns by storm? What am I missing here?

I think a lot of people are skeptical that they do as advertised. I know I was until I heard 1st hand from people that have run them. From those who I know have actually run them, they all recommended them. The only negative comments I have heard are from those who haven't run them, all 2nd or 3rd hand kind of info. As I said, I can't comment on actual performance gains yet, and actually I won't be able to compare it to a baseline anyway, but I can tell you I don't have a lopey idle where I know with normal lifters I would.
Another thing may be people don't know or think about them helping reversion.

Ok Am I missing something here? You guys seem to be making a big project out of this problem. I am running a 502/502 cam with a very tight 110 lsa I took my Stainless Marine risers and lengthen the exhaust tube 12" and I have no problem I also did this with a set of Gils on a blower motor. Am I missing something here?
