should be the same lifter, I can measure the body if need to ?

Runina, how many hours on the valves/lifters since last rebuild? I have a pair of 500EFI with 250 hours and trying to gauge if its 'time' or not to get the top end done....

I did my top end at around 200hrs, only because I was getting a little water reversion because of the silent choice set up and I had to pull the heads anyway because one of the exhaust ports was showing a little corrosion from the water. Did away with the silent choice and it's been all good since.

Thanks, i assume your application is salt water? I am fresh water. Going to have leak down and compression done and see where i am at and make a decision then based on the numbers.
