Heeders . do you need special ones for D port

[ONyX]

Hery guys just want to double check , do you need D-port headers for D-port heads or can you use regular headers for D-Port?
Thanks

Call the header company and find out for sure. I believe you do.

You should get the right ones. Adding spacer plates and modifying the setup is such a hassle. Please get the right ones if you run the D ports.

I had Fastburn D port heads on my old 406. They worked ok with Hooker 1 3/4" headers. Another buddy is using the same headers on his 406 with AFR 195 heads.

i have 1 5/8 headers not sure of the make they were on the car when i got it. There ceramic coated. So there prob to small to use, ill have to look up the size of 1 5/8 and go from there.

Acturally you are better off withg round header on the D Port Heads, Because the round header on the D port will create anti Exhaust reverision. That Mean the Exhaust gas will not go back in to the Cyl.

the guy who did the heads when my dad still had the car ovaled the exhaust ports out like a putz,the guy who just did my heads is friends with mondello from WAYY back and told me that the heads are pretty damn worthless seeing as he ovaled the exhaust port out and cut the port floor out of the exhaust. he said NEVER oval them out and cut the floor. he told me he would of enlarged the exhaust yes but, without cutting the port floor out <notice they make raised runner heads> and make them d port. he also said that with it being ovaled with no floor there is barley any scavenging effect on the exhaust.
