Fitting an Offy 4 barrel manifold on a 59L

[russcc]

Are there any issues with installing an Offenhauser 4 barrel manifold on a 59L engine. I plan to use the stock 59 fuel pump & stand, and was wondering if the stock 59 pushrod would work with the Offy manifold. I have 2 of these manifolds, ones looks like it is an earlier one without the oil fill and breather vent holes, and the other likely later with them. I measured the height of the fuel pump stand boss on both, and they were the same height. Thank you Fordbarners.
