B1BS HEADS ARE GREAT TOO.IM MAKING 842 HP WITH THEM.




I would second that!

Brodix makes the B1-BS head and I have never had a problem with them. They are real good if you open them to the Max Wedge port.




The B1-BS heads are good, but the small 65cc chambers would make a 500" engine with flat top pistons about 13.9:1 compression, which may be good if using race gas (or not too good if using pump gas?). OOB they don't flow much different that a RPM head, but can be ported to over 350cfm with maxwedge port size.

I have a set of used B1-BS heads with one damaged port/chamber. I was going to have them rebuilt and ported, but got the Victor heads. If your interested in the used heads, I'll sell them for $1,000 (Less than the cost of one new bare head.)
Here is a pic of the bad chamber:
