Guys;

I'm new to running Novarossi engines (I'm normally a Picco fan) and would like some advice.

Several People at the track told me that NR based engines will detonate on 30% and anything less than about .024 Head clearance. On my Picco engines, I have always set clearance to .018-.019 on 30% and they ran great. I would like to increase the compression to get a little more grunt, but don't want to damage a almost new engine by too little head clearance.

Any suggestions or comments are welcome.
