My cooling head bit the dust (seems to be a common problem) - I got a pair of Nova P5 heads but they are too thick in the button area. I gave one to my cousin to get machined down at work, but in case that doesn't work out, is there any other affordable head options out there that are a direct fit?

i think that older GRP and Sirio cooling head would fit...

Sirio and Novarossi have the same bolt pattern, the P5 head should work. I ran a odonnell head on my old sirio motor and a friend runs one on his Werks B5 so I know they work. All sirio based heads will work. Go to Ebay and serch cooling head http://cgi.ebay.com/TEAM-ORION-21-EN...item27b2a58f03
.99 for this one with 12 hours left it will fit.

What are you guys doing for run time with the extech .21. I'm running the bigboy pipe in buggy and can't seem to get 5-6 min max. Any help would be appreciated.

The big boy pipe sucks a ton of gas. The best pipe for that engine for power plus fuel is the 2013

You can use a nova head as well. Its a direct fit.
