273 Headers (weird combo)

TTI work fine for me, I would expect others to fit, but not ever as well from my experience, you have a tough decision to make bang vs buck in a short-term situation.
My experience is with a stock head 273 in a 62 Polara500 (Dart).
Yea I agree. Eventually I am trying to get to twin turbo but the dollars are not there right now.
