1g manifolds

[drfinest1809]

will a 1g after market manifold bolt on to a 2g head not concerned about port size just want to know if they would bolt up..

Yes the bolt pattern is the same.

Intake or exhaust? (they both fit, I'm just wondering which you we're reffering too)

intake but thanks cause i was kinda conserned about the exhaust also so shouldnt have problems then with the flanges

Well if your trying to install a 1G intake manifold on to a 2G head....for it to work properly you will need to get the 2G head intake ports, ported out to the 1G intake manifold Runners size. Also, just for reference the 1G manifold does not have a opening for the 2G MAP sensor. This means you would have to tap the manifold to create a source for it. If you want to install a 1G Exhaust manifold on a 2G head it will bolt on fine, but the same scenario as the 1G intake manifold applies except the runners on the 1G exhaust manifold are smaller than the 2G head exhaust ports (this is because the 2G exhaust manifold runners are larger than a 1G). Just keep this in mind.
