I took the heads off one is ECZ-G and the other is a ECZ-H. I need a matched pair either a G or an H. Can anyone help me find one. I would like to find a G to stay original.
 
ECZ-G heads show up on EBAY pretty frequently. I don't thing there is any such Y-Block head as ECZ-H. Are you sure you have the number correct? There is a ECG-H head that was used in 1956 on 272's that has a very close sized combustion chamber but has smaller intake vales that the "G" head for 1957.

Posting a 'wanted' ad here on FordBarn in the Swap-Meet section can't hurt.

Here's a link to a chart of head casting numbers.
If you haven't already seen it, this website has a lot of other very helpful info so look around there.

The ECZ-G heads are the most desirable ones, and priced accordingly. Hopefully a single one may be priced less than 50% of a matched pair. If the car will be driven a fair amount most folks recommend having hardened valve seats put in when doing a valve job. Ask the machine shop for an estimate and be sitting down first.

FYI: Even tho the heads are 99% interchangeable from left to right side of the engine there is a slight difference, the threaded water temp sender fitting.

"Left and right hand heads. Although all Y-Block heads can be installed on either side of the block, after years of exposure to coolant the .906" holes at the front of the intake surface will not accept a freeze plug. When choosing heads to be rebuilt be sure you have a usable left and right. When installing heads be sure the corroded hole is located toward the front of the engine. Be sure the hole at the rear of the head will accept a freeze plug or a temperature sender bushing. The corroded hole can be reamed to a larger size and an oversize plug installed. It is very discouraging to have 2 heads ready to install and find that they can’t be used as a set."
