Dan.  I missed your posting on the last page.  Let's determine whether the ECZ-G head that you posted the picture of is posted or un-posted.  If it's un-posted I can match it and it'll be yours for the shipping expense.  IF it's an un-posted big letter 'G' series, I'm sure I've got a driver's side head that has not been previously milled and has no pitting on the deck surface or in the combustion chambers.  Valves will be original Ford and margins will suggest that they haven't been ground before.  Probably easiest to ship the head assembled with springs, retainers, and keepers.

See what you've got, Dan.

To follow up on Paul's comments here is an interesting article with pictures of what Tim McMaster suggests doing to the C1TE or COAE cylinder heads to improve their performance on the street...

Food for thought.

Dennis: There are other Australian members on this site. Possibly one of them could help you come up with a matching head, either one. If for instance you found another COAE head, another less expensive route might be to contact J. Mummert Machine in Calif. (see the links from here) He has oversize 1.84" intake valves that fit those heads. That & as mentioned U could also plane them to up the compression & it would work out nicely..

Noshortcuts,

I'd be willing to have a head shipped over, I have already figured out that this engine is going to cost a lot of money to rebuild the right way and I have accepted that, the y block bug has got me and I now have a love for them! So I guess I'm on my way to being a true Y BLOCKER! Haha. So if you have one I'll be keen to see what you want for it!

Maybe send me a message.

Thanks Dan.


Thanks, Dennis.

Ted, noshirtcuts,charliemccraney,

Thanks for taking the time out to sit down and answer these novice questions I have.

I have noticed the great support this forum has. I think it's unreal, there is know way I could learn what I have learnt in 6 months without this website and its generous members. I remember posting when I first got the engine six months ago, with photos pointing at bits and pieces on the engine asking what's this, what's that?! Unknown to me at the time Ted was one of the first to reply, later on I just happened to stumble upon an article wrillen by Ted and I thought... Hold on a second... This guy is building some of the fastest yblocks around and he just answered my post telling me I was pointing at a road draft tube!!!! Unbeleavable!.

So anyway thanks for the support.

I'll throw up a few pics if anyone wants a look at what I'm doing.


Engine when I got it
 


Coat of paint and some headers. (This is before I knew anything, just thought I couldn't hurt with a clean up and a coat) reverse rebuild!
 
 


Stepped the frame in to fit the Jag IFS nice and comfortablely.


Thanks, Dennis.

Dennis.  I was hoping that it was practical to help you out with a cylinder head.  In working with a Forum acquaintance in Australia a couple of years ago on some y-block parts, it was astounding what the shipping customs' issues were.  I can't imagine what it would cost to ship a 60 pound cylinder head with hardware to you.  Correct me if I'm incorrect on my assumption...

I get a number of core engines here where the heads are mismatched.  While the engine may not run smoothly, I don’t see it being something that will hurt the bottom end of the engine in the short haul.

Ok thanks Ted,

I think ill put it back together and get it running, meanwhile i'll look for another ECZ-G head to pair up with the existing. It should be ok for the time being, the truck won't be on the road for another few years.

Do you think there will be a detrimental effect on the engine in the long run with these different heads, or will it not know too much of a difference?


Thanks, Dennis.

The idle may be a bit rough with two different heads on the engine.  The ECZ-G head would be the better of the two heads on the 272.  Using the COAE head will have the compression ratio lower on the 272 versus what you would find on a 292 engine.  Another option is to find another COAE head and have them both milled so that they are both the same cc's and with smaller combustion chambers to bring the compression ratio back up some.  If it’s any consolation, the 1957 272’s (U.S.A.) did come with the ECZ-G heads.

Charliemccraney, thanks for the information, that might have been why, out of one exhaust manifold there was the slightest amount of blue smoke. I noticed this when I had the engine out, trying to get it running. Also with the timing, I just couldn't get it right, not sure it the miss matching heads were to blame there.

Noshortcuts, I'm in Sydney Australia. Which makes it hard to get my hands on a lot of the gear you guys have readily available.


Thanks, Dennis.
