ID of water outlets on pre-49 heads
 

Like the title says, I would like to get some input as to the inside diameter of the water outlets on pre 1949 Ford V8 heads. I would like the measurements for as many varieties of heads as possible; stock, aftermarket, cast iron and aluminum.

I need the information for a project I am contemplating. So if you have a head handy, could you throw a tape or caliper on it and let me know what it measures? Thanks.

Hose I.D. is 1 3/4".

To make things clear, I need the ID of the outlet on the head, not the hose.

1935 head ID opening is 1 7/8, pump is 1 1/2. On both head and pumps I find a variation of about 1/32 in.

Surely someone out there has a 59A, 81A, Edelbrock, or Offenhauser out there they can throw a tape on.

Pair of 81A (A) heads measure 1 9/16"

59AB = 1.9 OD and 1.565 ID. The dimensions vary a bit due to the roughness of the casting.

Thanks, guys, that's enough to get me started. Any others will be appreciated.

Navarro, new in 2006, bought them from Barney before he left us. ID 1.385". Have an old set of Navarro's, but can't get at them to measure yet. May have some stock ones, will check and report back.
