I have a set that was just worked by John

I decided to go with the aluminum instead.

Theses heads are bare.  NO Valves.

Valve guides, with positive seals installed

hardened seats on intake and exhaust.

Spring seats cut for high pressure springs.

Asking $750 OBO    760-315-0542.  Will ship.

ECG-Z? or ECZ-G

Hard seats Intake and exhaust

Surfaced -.025 Combustion chambers would be 66 to 67 cc as per JM

Guides shortened for high lift springs.

Pete,

Please answer a couple of questions regarding the heads you have.

1) there are three species of 'G' heads. The casting letters ECZ-G are either small or large. Which do you have? Note: The intake and exhaust porting is different on the two... different cores were used in making the castings.

Also, IF the heads have the large casting letters ECZ-G they may be early or late heads. The early heads are not posted while the late heads are. Do you know which you have?

2) has porting work been done on these? By John? If done by John, are they 'Street Port' or 'Race Port'?

3) were hardened seats installed for original size valves or for the oversize diameter valves that John sells?

Thanks.

2) has porting work been done on these? By John? If done by John, are they 'Street Port' or 'Race Port'? I will check with John Mummert to see which and what porting has been done.

3) were hardened seats installed for original size valves or for the oversize diameter valves that John sells? original size valves

Thanks.
