yes this debate as a bodge will go on for ages lol
yes if you go by the book it is technically a lash up theres no doubting that.
but if done properly and using the right material it does work and shims will stay correct for thousands of miles.
my track engines covered 3000 miles of being caned and shim clearances are still spot on and you don't get a harder proving ground than on a race track.
if you have or can get hold of correct size shims then fit them you would be crazy not to!
but if not available then either use the car with noisy loose shims at risk of throwing a rocker or garage the car until you get them which could be ages lol
the initial thread I did years ago was done to help people out of a situation I had an answer for at the time, many many people have either done their own cars and weve done a fair few over the years.
if it didn't work do you honestly think they would be fitted in my engine which cost me a hell of a lot of money and time to build............don't think so
so its a pointless debate really
