Brodix BD2000 heads--Pro and cons

[glnrcg]

looking at a motor that has 13.5 degree BD2000 heads.How do these compare to others such as sb2.2 or the newer 13 degree heads by dart. Horsepower and torque curve good for dirt late model???

.The bd2000 is better than the 13* but not as good as rhe SB2.2.As far as what the hp and torque curve is on any particular engine,it all depends on the camshaft profile and rocker ratio that the builder used.A good example is I know of some 9* 450ci engines that wont get out of their own way.
