big block b headers in a body?

jwatkins,
The best advice I can give you is to buy the part you need.
All the advice here is good,but with out knowing more about your build it would be hard to say which header is best for your build.
I have Schmacher's,Super comp's,$1200 tti's and the lowly Headman B-body headers in my car's.

The car's range from 11 sec cars to a 9.25 car.
Buy the part for your build.
