Not sure if anybody caught the one thing I wrote up in the second picture about the Woods push rod cup. It sits inside the plunger where the OEMs sit on top of the plunger. And what I found was there was .013" clearance between the push rod cup and the plunger on the Woods..
Don't you think that that would be a big issue with the lateral load by the angle of the pushrod on that cup in the plunger?
Hopefully the new platinum lifters cure that problem...
If I'm buying them, 2313 for stock valve train and 2313SE for performance valve train.
2313 should hold up fine. 2313SE gives more insurance with slow leak down, and oil ports for the roller pins. To me the 2313SE price isn't high enough of a difference to use the 2313.

like it says..
I decided to compare the OEM lifters I took out of my twin cam, my 2013 to the woods alpha lifters and this is what I found..
Woods is on the right OEM on the left..
I got to tell you I know that top line / iliff Johnson makes the lifters for Bob Woods however I was not impressed with them at all.. I thought the spring for the plunger was weaker and the cup which is separate from the plunger is wicked loose in the plunger. . Bose plungers fit the lifter with pretty much the same amount of clearance.. I personally feel that the woods alpha lifters do not deliver as much oil to the top end as the OEMs You'll see all my measurements below or above whatever.. The rollers and the needle bearings appear to be identical..
Take note of the measurement of each plunger and you will see that the woods alpha has a larger diameter piston than the OEM which I believe takes too much away from the sidewall of the lifter body.. Not only that even though the springs wire size measures almost identical the OEMs have a much stronger compression on the plunger than the woods. The Woods were like hardly anything..
Now if you take a look at the diameter I measured with my micrometer on the plunger bodU OEM I got .6155.... Is that the older style b lifters or the newer style C lifters?
I did not disassemble the S&S premiums that I have so I have no idea what the measurements are overall for those lifters compared to the OEM or the Woods... However what I do know is that the S&S are nice and quiet and the woods failed on me.. They were so noisy It was hard to believe and I wasn't expecting that because even in their advertisement they say Cam lift does not matter as compared to DMH where they're only good to 0.600"...
I will be trying to get some type of replacement from Hilift Johnson, these lifters failed with this new cam the T-mann 660ps2 in 150 miles and they're just a year old it shouldn't have failed but they did...
If you take a close look at the picture it even looks like the spring for the woods lifter on the right actually bent...
Let's hear your opinions always willing to learn something new. But I think the Woods lifters suck...
What I'm really trying to find out here is are some of these well-known people in the industry that are putting out lifters on the market, are actually a reliable product that they're putting out..
I personally never had an OEM lifter fail, be it a twin cam or an Evo or even a shovel.. I will take motors up to 6500 RPM without a bat of an eye but for some reason I think these Woods lifters are nothing but a push of propaganda that are crap.. I can't believe they didn't hold up.. And I'm not just saying one but both the front and rear cylinders could not handle the amount of lift that the t-man 660 PS2 cam has.. Another thing I'm wondering is if these are just a cheap copy of the Hylift Johnson's..
To all of you guys using the Hylift Johnson's, If you could take one apart and post up all the parts I'd love to see it and if you want to take the time to take measurements I'd appreciate that as well..
I would really like to get a fair evaluation of what is what and this is the only way we're going to do it...
Thank you..

I won't run a camshaft in a street driven bike with a lift over. 580 because it is abusive on the valve train and the geometry isn't conducive for a long life. Just my personal preference...I don't like riding a real fast hand grenade on the street.
