Im putting together a 1984 302 and bought speed pro hyperthetic pistons. I have a pair of 1968 289 heads and hoping there 58 combustion chambers. Does anyone know if they are. If they are 58 so I can have around 9 to 1 compression ratio.

they flow more then the e7 heads but if you could get some 69 351w heads you would be in better shape for flow.

yeah they also could be 54cc i believe. i would have thought you'd get more compression than that. i have a set of 66 heads and they are 54cc's.

Not to hijack, but how much are a set of 69 351 heads worth?

I know a guy with a 69 351W block and heads... He says that they are from a MACH1, but I have no idea how to tell, or if they even came with a 351W as a option.

a friend had some D0oe heads that were slightly ported and sold them for 350. look for somewhere around that price.

68 heads could be any where from 58 to 64cc, you have to cc them yourself.
there are a few articles here on how to do that, and how to port the stockers:

The 68 heads are most likely the 58 cc or larger, as thats when the 289 morphed into the 302 and smog became a concern. Best bet is to cc them yourself. Set a head upside down on a bench, shim it level, and fill a chamber with water from a measured container, and you are there. That should be close enough to tell the difference.

Are you sure about the E7's flowing less? Stock non Hi Po 289 heads don't flow well at all......I doubt they're better than E7's.

just letting you know that the hipo heads are the exact same as the regular 289 heads with the exception of the valve springs surfaces and screw in studs.

You should be able to figure out which heads from the markings, that chart should show you what the
volume is... Looks like all the 289 heads were 59.9 CC that year unless I'm misreading something.

I pretty sure they do flow less unless the data i have found on the internet is wrong. Here is the link go down to the ford section under windsor.

69 Mach 1 was only the 351W engine 4V... it was the first year for the W engine.. the heads will be coded "C9OE" and they are a good head.... HOWEVER.. they WILL need hard exhaust seat and probably Valve guides for the unleaded fuel. so keep that in mind when you buy them... cool?? GT40s will run circles around the C9's and D0's and they are already set for unleaded...
just a thought...
Just me..............................
