Conversation Between heeltoedrver and theblackmamba

Whats up heeltoedriver? I have a question for you regarding your Picco Red Dot .12 that you use for your CRT .5 Jammin. I was reading some of your threads and I too have a Crt .5 and Picco .12 (not a red dot) but it has a red head and cost approximately $130. I cant remember what the model number was but anyways..... did you ever take the shims out of your motor? Obviously, I'd like to increase the performance of my motor and thats the reason for taking the shims out of the head. FYI- I am currently running 30% O'Donnel Fuel and wondering if taking out the shims would be too much stress on my motor. What do you think? Any advice regarding when/ when NOT to shim a Picco .12 would be greatly appreciated? Thanks Steve
