rather than running heavier springs I'd prefer to run a Rev Kit -
in the lifter valley.
it's old school - but takes the weight of the lifter off the valve
springs - and that makes sense.

I've never heard of this before, please elaborate!
“ULTRA REV KITS” • ROLLER TAPPET (PATENTED) Isky Invention
Invented by Isky in 1958, the original "ULTRA-REV KIT" has now
been copied by most other cam grinders.
A tribute to Isky's
Engineering Designs.
The "ULTRA REV-KIT" is engineered to increase engine RPM and
prolong roller tappet bearing life by pre-loading the roller tappets to
the cam lobe (eliminating stop-start "Skidding".)
Pre-load springs are held in place by lightweight aluminum retaining
bars which install beneath the cylinder head (a drop-in installation).
Special Note:
Included with every set of 1241-series Roller Lifters is a package of P/N 200-RTW Roller Tappet Washers, designed to protect your
Roller Lifters from Rev-Spring “chaffing”.
They are also available for sale in replacement form as well. P/N 200-RTW...set of sixteen (16)
pieces.
ULTRA REV KIT: A device designed by Ed lskenderian .to preload the roller tappet to the camshaft to allow higher rpm. The kit consists of 2 plates which are located on each side of the valley chamber and a spring for each roller tappet. The springs fit between the roller tappet and the valley plate.

but has all the 'other' items necessary:

Go to the Isky site - 'Online Catalog' - it'll open .pdf - go to:
rev kits pg.23
CRANE CAMS has all the parts for their previous AMC 'Solid Roller Lifter Rev Kit' - available - except the 'Spring Plates' - .
Thanks!!

A rev kit for an AMC V-8 would be an excellent new product idea. I will buy the first one !
As an added benefit I think that the rev kit will keep the lifter from popping out of the bore and uncovering the oil galley in the case of a valvetrain failure.
Calling MC !
i have a old crane rev kit for a amc.
i will check and see what it would cost to mill some.
i will post what i find out.

ok, estimate on making billet spring plates patterned from the cast crane ones is 180-200 for a pair, if we can get several sets pre sold.
thats just the spring plates.
if we could get several commitments for them that would be nice.
it will cost quite a bit to make the jig and do the program just to do 1 or 2.
shoot me e mails if your are serious about these.
we are currently working on a 2 piece amc valve cover also.
let me know if anyone hads interest in these as well.
thanx rick wyman
