No real way of telling at this time, unless you feel like pulling the intake. Adjust them again and watch them for a bit and see if they loosen up, hopefully you just messed up last time. Also if you feel like it you could cut open the oil filter for a look see

No way it wore the intake cam lobes only,and exactly .038"-.042". My bet is that during lash the intake lobes were not positioned at the base circle of the cam when lashed. Doug
entirely possible. My lsa is 108 and i adjust them by popping the starter to intake closing- adjust exhaust. exhaust opneing- adjust intake. so im never on exact same place. Maybe I need to do the rotate 90 method..... It just such a pita with the 1/2" drive socket and ratchet down there and doing it from the top.
how do you all turn your motors over? from the top or the bottom? (I guess most of you all dont have a big honkin clutch fan in the way like I do)

well if that is the way you adjusted it it is very possible you were not on the bottom of the lobe. Do the 90* method. I usually turn the motor over from the bottom because for me it is easier. See what works for you.
I could be wrong and I probably am, but isn't the 90Degree method the least accurate when it comes to these performance cams. I know on my last couple using the 90degree was way off. The last two cam profiles I had I was adjusting the intake when the exhaust just opened and I adjust the exhaust when the intake goes fully open and just starts to close.

Looking at the pic it is possible that you doubled up the feeler gauge like you suggested. I would set the lash again and go from there

This may seem dumb but pull some of the adjusing screws out of the rockers and check the balls and see if they are all the same. Thought I had a cam going last summer and started to tear in down at the track and happned to notice the balls on the ends of the adjusting screws were wearing real bad on some of them. I was running Cranes at the time and happened to have some spares with me so I was back up and running for last time trial

I will check them for sure.
I recall RAS telling me they replaced some of my adjusters when they rebuilt them. not saying these are the replaced ones or the originals but heck, anything is better than a flat cam. even a doubled feeler cluster muck

check out the difference in the amount of screw thread showing between an intake and exhaust...
steve , when checking screw length difference the important thread count is the screw threads showing on the PUSHROD side , you want no more than 3 on the bottom side .

ya I know that and Im good on that. I put the picture up to show how i may have screwed up the adjustment of those intakes. They have more thread showing than the exhausts by a few threads- ie, they are looser

I believe you just messed up when adjusting the lash, like you show the intakes are showing more threads ON TOP.... re-set the lash and have fun beating on it
