Wow, just the opposite of my problem. Well, it happens. That's a pain that you have to pull it all apart again, but I guess it's the only logical thing to do. Yes, going with a tighter LSA will make it worse. If you're not running the thing at 7K, you can run the intake pretty tight...I know several guys who get away with .060, even a tad less...but it's taking a risk of course. Is your intake valve hitting the entire flat part of the piston dome, or is it just kissing the edge of the cutout?? Can you tell? This is a very common problem with those brand pistons. If you do the clay method, as well as the dial indicator, you can actually see what is hitting, sometimes that can be a help. Im going to send you a PM with some info on cam choices...Im working with a guy who is grinding my new cam (as we speak, hopefully) and seeing as how Im having basically the same problem as you, he asked me to take some measurements, and he knows by those measurements what the clearance will be at all times...we did the cam specs based on that. I think you will be interested to see what he has to say. John
