Pinto e-max inlet port size

Hi all,
Trying to buy some pinto stuff off a guy but due to being in lockdown I can't view the parts.
Struggling to find out if a head he has is a normal 1.6 pinto head or the emax head with narrow ports.

I've had an emax years ago but can't think how I can get someone else to establish the type of head he has.

Anyone think of a definitive way I can get him to establish what he has or anyone got the port sizes of the standard and emax head to compare.

Thanks

Po.

From the web:


At the beginning of 1984, Ford Pinto engine displacement range switched from 1.3/1.6/2.0 to 1.6/1.8/2.0. The newly introduced 1.8 L engine used the 2.0 L crankshaft, so to uniform engine parts for the whole range after dropping the 1.3 L the 1.6 L was redesigned to also take the 2.0 L crankshaft which had a 76.2 mm (3.00 in) stroke. This of course led to bringing the bore down to 81.0 mm (3.19 in) to keep the displacement within range it was now 1598 cc. The TL16E became now the only available 1.6 L engine of the Pinto range. Although the compression ratio was raised to 9.5:1, the power figures did not differ much from the earlier TL16H version the engine developed 56 kW (75 hp) of power and 123 Nm (91 ftlbf) of torque. This engine is sometimes referred to as 1.6 E-Max engine.

You should be able to identify the age of your engine from the engine number. If it's after 1984 it's an e-max one. Also there is a date cast into the top of the head next to the head bolts in case it's had a replacement head.

Yes but how many times have engines had head swaps?
He doesn't know the engines history, photos are not clear so the only way without me physically going to look at it ( I'm in lockdown plus it's too far to just pop over) is to know the emax port size to compare with his head.
Thanks,
Po.

Maybe but I'd argue that whipping off the rocker cover and looking at the manufacturing year is easier and more accurate than measuring the ports. You can see on mine, it's cast into the top of the head and easy to see. It's between the inlet ports of 1 & 2.

My engines inlet ports are slight ellipses 38mm x 40mm, note they are cast into the head not machined so vary slightly. I don't know if they were enlarged over the years but my head has not had any porting or machining done. Hope that helps

Mr Whippy,
I'm foolishly miss read your first reply and not sure how I did.
I wasn't aware the date was cast into the head so that is a new one on me and a great help to!
That info should be the easiest way (as you rightly say) to establish what head out is.
Thank you and truly sorry,
Poe.

I don't know exactly how big the E-max ports are but once in the cylinder head (not just at the flange) the 1600 and 2 ltr "old version" heads are approx 37mm. The E-max is a LOT smaller. It's a huge difference and they are also not round inside. The last one already tell you it's E-max or not.

If you can send a picture of the inlet port I can see it from miles ahead.
