    Regardless of all appearances, I would have any or all lifters checked for proper hardness, i dont know what that number is,would guess 50+ Rockwell "C" but you could take to any good machine shop/ tool and die and get the hardness checked, it only takes a min to do, and the cam could be checked also, if they are only surface (case) hardened, would have to do a different hardness test, not sure of the best test for that, especially if its a shallow case thickness, all bets are off with the Chinese.

    I have the same issue going on. Wish I had bought my parts thru Jeff. I'll be following this with wrapped attention.

    Can’t say enough good things about the support and products we have gotten from IHPA. :yes: We received the replacement lifters for our build Friday and took a few pics just to add for comparison.
    Good lifter on the right in these shots.

    We did note that the hole for the inner cylinder/pushrod cup was a smaller diameter. .646" for the Chinese lifter and .683" for the replacement.

    I wonder what supplier Comp Cams uses for their IH-application 'Hi Energy' hydraulic lifters...?

    There was rumor awhile back that they were made in India but I don't remeber seeing any actual evidence of this. In all the thread digging I've been doing here and everywhere else I see a lot of complaint especially about noise with the comp lifters. Tom Mandera seems to be doing ok this time around with his although he's dealing with trying to find a mystery noise. But jury's still out on that so far. After all I have read I personally will use nothing but Johnson Hylift lifters in a IH engine. I also will be buying from IH parts America any time I can. There service speaks for itself obviously.

    Oh and I gotta agree from the pics it sure looks like the China lifters are a intentional knockoff of the Johnsons. Considering sealed power used to use johnsons under their name and the. Started selling their own Chinese knock off I kinda think it was intentional. Someone sold them on hey it'll be cheaper and no one will know the difference. I don't bother contacting companies often but I think I am going to see if theirs a way to send seald power a e-mail just to tell them they are now selling a inferior product. It makes me wary of all their products now. Kind of a shame they used to sell a good product for a reasonable price.

    Here's my comparison of Chinese vs American lifters:
    [​IMG]
    Chinese left, American right - Click to enlarge.
    I see rougher casting and a weird circular pattern in the Chinese one.

    Also checked out the other 7 lifters today - they are undamaged and show a wear pattern that indicates proper rotation.

    Same rough casting and another circular pattern on the Chinese one.

    I have been following this thread as I am currently rebuilding a '67 304. I was planning to use a Comp Cams cam/lifter kit but after reading through this thread and Comp Cam lifter reviews, I decided to order the Johnson lifters from IHPA. I saw someone was asking where the Comp Cam lifters were made, well I have checked all over the box and paperwork and there is no "made in..." markings anywhere. Yet on their cams, valve seals, timing sets, and valve springs; they have "Made in the USA" on them. This leads me to believe they source their lifters elsewhere. First two pics are the new Johnson lifters I received and they are a beautifully made part. Last two pics are of the Comp Cams. No polish to them, running your finger over the side you can feel a rough surface, and just an odd discoloration to the metal; no uniformity. image1.JPG image2.JPG image3.JPG image4.JPG
