brodix bb3 cnc or bb2 cnc

I am in the process of building a spare long block. My current setup has the brodix bp bb2 extra cnc 355cc heads. I contacted Brodix yesterday and they said that i should upgrade to the bp bb3 extra cnc 366cc head. Has anybody else tried the bb3 heads?

I rebuilt a pair of merc dry sump 900's a few years ago and put those on with a bigger cam and it picked up about 10 mph in a 40 Skater.

I use them on my 598 and it picked up 5 mph. Didnt lose any acceleration. With your blower set up I bet they would be amazing.

Stay away from square port heads. Try to stay under 360cc runner it will have better usable power take my word for it. I had bb2+ went to BB3XO 351 Than to HH383MC The BB3XO where bad aSs.
Made 930hp with the BB351XO
