The dynomax headers are good but you may need to double gasket or run thicker gaskets at the heads. I always run the thick ones. The ceramic coat doesn't last very long.

So anyways, back to SBC to BBC conversions:

1) If stock manifolds are used (and i now know that they aren't in this particular case) will they (the BB's) bolt right up to the stock SB exhaust system?
