MG MGA - Block heights

Hi all.
Is there a fitted height difference between 1600 and 1800 blocks?
I am waiting for my 1800 engine and wondered if I could fabricate the tubular exhaust manifold using the 1600 engine. I have a 1800 tubalar manifold that does not fit , but a cut and slight lengthening of the down pipes should sort the problem out.
Thanks for any help.

Hi Simon

I've just measured a couple of 1800s at 12 & 5/16" from the underside of the sump flange face to the top of the block.

Thanks Dave. I will let you know what I find tomorrow.

MGA and MGB blocks and heads have all the same exterior dimensions for the mating surfaces. Starter positions are variable in the rear plate.
