Mikey Posted May 19, 2008 Share Posted May 19, 2008 Ok, well i really dont know here, im confused and cant find my answer by searching... on my n47 head, should i be using a round port exhaust manifold? and should my gasket be round ports as well? cuz the gasket i got for it (for a 77z) has not square, but more like hexagon shaped holes.. i dont want any leaks so any info is appreciated. -Mikey Quote Link to comment Share on other sites More sharing options...
PresaMax Posted May 19, 2008 Share Posted May 19, 2008 I have a N47 head on my '78 280Z and its definitely a round port exhaust. Unsure about the gasket. Julius Quote Link to comment Share on other sites More sharing options...
Challenger Posted May 19, 2008 Share Posted May 19, 2008 n47 With gasket. It obviously round port, and so is the gasket, so Id use the round port manifold although Ive heard of people using the square port manifold on the round port head.

Mikey Posted May 19, 2008 Author Share Posted May 19, 2008 you wouldnt happen to have a part # on that gasket would you? a n47 is from a 77ish 280z right? Quote Link to comment Share on other sites More sharing options...
