need a opinion,been running a br6 ngk with a 175 shot for few years now, going to up my shot to a 200 to 225, think i need to go with a br7, or is the br6 ok, i usually run around 22 degrees of timing on the spray.

You should have been on the br7 already. You will have to go to the 8 for 200-225.

Depending on fuel octane a 7 will be sufficient.
