While these headers look interesting, my feeling is that the primary tube diameter is too large to optimize performance of our 413's, unless you have a larger than stock cam and high flow aftermarket heads. I think 1 3/4" tubes would be about right for our cars. Let's hope TTI makes them available in that size. Until then, I'm sticking with my HP manifolds.

They are designed to fit stock cast-iron cylinder heads or Edelbrock aluminium heads, and the exhaust systems are available for wagons and passenger cars".
