I got hold of some ATR cams to put in my H22A 4th JDM. I believe there is an issue with the LMA's. I have read that you can put a shim washer with them but there is also an alternative spring LMA which is a retro fit for B18's. Can somebody tell me where I can get these please. And if what I'm thinking will work.
Cheers

I had the issue with my crower cams, but skunk2 would have been fine.

also with the higher lift I was advised to go for the B18 spring type LMA's

I think the ATR cams you wont need the shims,

give perfomance autoworks a pm, they done my work, they can also provide the parts
