D Port LS swap headers
Hi guys. I'm doing an iron ls1 swap with 243 heads which has D port exhaust chambers. Do anyone know who/where I can find a set of long tubes? All the pictures I've seen for the swap headers are oval port

Nevermind the exhaust port shape. The round headers are what you want, and use LS1 style header gaskets.
For what it is worth, all LS1 engines are aluminum. You have a Vortec truck engine with a head swap. Should run good!

By using a different style port it wont cause any leaks?

No leaks. 243 heads were actually on Camaro SS in the last couple years. You definitely want the LS1 round port headers.
