M10 Manifolds Question

[sleeperviva]

Howdy!

Will the small port M10 manifolds bolt onto a big port M10 head?
I have just finished building up the replacement engine to go into mine and before I subject it to boost I want to run it in over the winter and was hoping to save time and just run it on the existing parts of the old motor until im ready to put all the injection stuff on
I know im gonna have to put a low-pressure elec fuel pump on as there is nowhere to put the mech pump on the new engine

Cheers
Steve

Yes it will bolt on but there will only be 1 or 2 mm cover in places so it might be hard to get a air tight seal..
