Get a pair(1 Int and 1 ex) set at the valve to whatever lash you want and then see what it is between the cam and the roller. A feeler gauge should work ......Once you know the number that is at the cam/roller with the proper lash at the valve tip..... set them all at the cam/roller contact area. They do make very thin open end wrenches once know as tappet wrenches that might work on the adjusters...

I agree that motorcycle engine mechanics would have tools to do this....My son has been around motorcycles all his life......

I also think Terry's idea of cutting the bosses down is a very good one......Not real hard to do it either.....
