Posted December 22, 201113 yr comment_375230 Hey guys!I am pretty new to this forum and have not posted much or anything. I have a '78 280Z with the stock everything....! When I purchased it for $1000.00 it was running as good as a 33 year old car can run. The previous owner was regular with minor maintenance, oil changes, lube and grease. Anyway, my point is, I am planning on doing some updates to my Z. Rebuilding or renewing the block and head components is one of them. So now my questions is i have a Manifold Bolt/Stud kit (P/N: 15-8081) from thezstore.com that i recently purchased to upgrade some hardware that was as old as the car itself. Well now i had the head worked on and i am kinda lost on where all the studs and bolts go in. i have more holes than bolts on the Intake and Exhaust side of the head and I was wondering if anyone knows where to look for that info, i have tried searching but i may not be wording it all correctly or searching with the right terminology, I wanna say thank you before hand to all of you and for all the great info you have on here for us Z noobs.

December 22, 201113 yr comment_375231 The heads are also drilled for carburetors as an alternative. Place the intake/exhaust gasket on the face of the head and you'll see where the studs go. The carb holes will be blocked. There are good drawings in the FSM also - http://www.xenons30.com/reference.html Link to comment https://www.classiczcars.com/forums/topic/41715-1978-280z-n47-head-intakeexhaust-bolt-and-stud-locations/#findComment-375231 Share on other sites More sharing options...

December 24, 201113 yr comment_375358 some threaded studs for the manifolds could have varying lengths depending on which part of the manifold flanges they fit through. This may make a big difference if you plan to use headers, but it may not matter if you are reinstalling the OEM exh manifold. When you're in there with a wrench head & clearances are tight, it could make all the difference. Mock up everything & test fit prior to reassembly as thoroughly as you can.
