Personally taking the chance of used lifters failing on a new cam is not worth the price of a new set of lifters. When I was young and broke I would have chanced it. Not today.

Here are pictures of a couple of different lifter tools for the Y.  The original boxes eventually fell apart and I’ve put these in some custom wooden cases to keep all the parts together.  You can see the troughs that are used to capture the lifters.  It’s wood on one of the units and metal on the other.  Both lifter tools swivel the lifter 90° when working the triggers.

Trend tool steel lifters, I think is what Cliff means.

If you want that tool, keep scouring eBay.  One is bound to show up.  But you need to be willing to pay whatever is being asked.  It's one of those things that you need to buy when available.  No going to the guy across town for a better price.  Probably not a solution for the time frame of the next several months.

All you care about is the crown on the lifter, if it's there means little or no wear, If your worried, get new lifters, the best ones are made by Trend, they never wear  and can go from cam to cam

Checked out Ebay for any Manzel tool that resembles the one you have, but nothing there. The other thing that concerns me about using my lifters with a new Isky cam goes back to Ted's information regarding the lifter bore angle. If my lifters are broken in on a Comp Cam which was ground based upon a 41 degree lifter bore angle and I install the Isky Cam which is ground on a 43 degree lifter bore angle, my lifters will not be making contact in the same position on the new Isky cam. Does this really not matter or is this a real concern?

Take out your lifters, put a straight edge across them, if there is any crown their usable, polish the foot with 600 wet/dry paper, do not sand only remove the glaze (shine), if any lifter is flat it needs to be refaced (most cam grinders can do it) around here cost is about $3.00 per lifter, however I don't like to do it, I think it removes the hardness, yes you can change the cam and lifters on the stand, there is plenty of room, you do not need to take out the crank. 

It took me 25 years to find that tool, it's not for sale, Ford sold them and almost all dealers had them, also KR Wilson and Manzel sold them.

To me.. Is it worth saving the money using a set of used lifters, no matter how many runs, versus having to replace the cam and the lifter if they fail.
Remember you break in an engine by seating the rings to the bore, the bearings to the crank, and the lifters to the cam. That means they wear into each other, so old lifters wearing in to a new cam just means additional wear.
I've seen new lifters fail during break in several times.
My opinion, yours may vary.

I say your existing lifters are safe to use on a new cam. Way back in 1963 I built a 312 for my '48 Ford. I bought a new cam (246 deg. replacement) and new lifters from the Ford dealership. I drove the car about 400 miles when a friend offered me a new 1957 factory "Blower Cam" (B7A6250C). I installed it and new HP valve springs without changing the lifters. That cam and those lifters are still in that engine with NO problems!
Don't worry about it!

Frank;

Thanks for the advice! Here is some additional information I have learned thanks to Moonshadow and Ted. Comp Cams are NOT a good choice for Y Blocks because of the lifter bore angle. Apparently, Comp Cams grounds their cams based on a 41 degree lifter bore angle common to scrub motors. The Y Blocks use a 43 degree lifter bore angle, so in my case, the valve timing was off. I think this is what caused my issue on the dyno. Ted provided me the Isky cam card he used with Chuck's build, so with Chucks blessing, I plan on having a new cam ground with those same specs. Bad news is I will have to replace the lifters also which requires a complete tear down of the motor. Well, the coupe is not done anyway so I may as well do it now...this winter.

Cliff, have you ever tried to use this tool set? It would be interesting if you could post pics of the individual pieces so we could do some brain-storing. Thanks, JEFF...........
