Yeah, i guess that was my round about question, if they improved since your original post, thanks for your opinion!
My current build also has the same trick flow heads, a cam not so far different, and I also bought my prw 1.6 rockers from Mike at B3 with his shim kit (great person/business to deal with).Hence my concern.
Since I don't see prw complaints here on a regular basis, I would think it has been corrected
