So, I have a question. If I order an exhaust manifold for a 12 valve engine, what shape would the ports on the manifold be? I received one today with round holes in the flange. Am I wrong in suspecting I have been sent a 24 valve exhaust manifold? I've only been waiting 2 months for this thing. Please tell me I have the right one.
 
why such a long wait!?? :confused:

you can port match it to a 12v if there's enough meat, but I'd get with the distributor and get them to send you a 12v manifold.
 
Same thing happened to me when I ordered one for the 12 valve. Funny thing is that it was drop shipped right from HTT.
 
I've been running ATS for years. No problem with ATS. This is something a little different.
