Thread: 3.5L/4.0L Inlet ports, Sizes??

I have a spare 3.5L (Fuel Injected) Inlet Manifold that I am going to Port Match to the Inlet gasket and then give it (port matched manifold) to the bloke that is going to fit LPG Gas Injection to my Disco, to predrill the holes in the manifold for the LPG injectors. I will plug these holes and install this manifold on my engine, ready for the LPG installation in the new year.
My engine is a 4L (crossbolt/10 bolt heads) engine with 3.5L timing cover, Dissy and EFI system fitted.
My query: Are the inlet ports on the 3.5L (14 bolt) head the same size as the 4L (10 bolt) head, is there any difference in inlet manifold gaskets, would appreciate any info, Thanks, Regards Frank.
