Did you ever have the motor or car on the dyno?
If not, I’d suggest you do......... see if you can nail down when the valve float/lifter unhappiness occurs, and keep the motor below that point. With a hyd roller(or hyd flat tappet)....... it often occurs at a lower rpm than you might suspect.
Running the motor up into the rpm range where things get unhappy usually results in things happening like what you’re experiencing.

I wouldnt double nut them.. 19 years is pretty damn good for not having the valve covers off.. you dont need the extra weight on the valve train.. you can buy a pair of rockers .. they have a tie bar for each pair

Some of these cameras that hook up to your phone or laptop send pretty clear pictures and are really cheap now. It could save you some time and money and answer all you questions.

I have one but its a stand alone unit.. I can put it down a spark plug hole to see in cylinders or any place that bigger than 13mm in dia.. works nice and was pretty cheap

Good luck trying to find lifters that are the same as what you bought 19 years ago.

Good luck trying to find lifters that are the same as what you bought 19 years ago. I looked the part number up and they are still available. You wouldn’t think they would be different and have the same part number. I don’t care about a little weight on the valve train,I don’t want them to come loose again. I think the last time I had them off was 2001. I don’t drive it much at all. Maybe 1k a year but back in the early 2000 it was my only Cuda so it got out more back then and that when I raced it!

Crane was bought out sometime back.. its hard to say for fact if they are truely the same without a call or measuring them.. also being that you are running a hyd roller your springs would be pretty weak and adding any weight would be a challenge to your springs.. but ask around

I will see if my springs are to heavy for a roller. I still have my paperwork from when I had my heads done. They are Crane springs part number 99098.

19 years ago Crane made their own roller lifters in house.
They have been sold at least 3 times since then, and have not had lifter manufacturing capabilities for quite a while.

My friends and I took a tour of the crane facility back in the 1970’s while on a vacation. There was a little old lady straightening pushrods with a hammer and dial indicator. Lol
