I don't think you will be able to tell by this pic but it's all I have at the moment. I'll try to post more later.

 

If it bolten into your FC and it's an NA it's a six port.

 

Looks to be a 6 port judging by the lower intake manifold. Yor can see where the actuators for the 5th and 6th ports used to be.

 

Resurrected from the dead, but worth noting.

Actually, the housings he's got are definitely old-school housings, which mean it can't be an FC setup with coolant o-rings in the irons. The only way to stack the motor he's got would be old school housings, 85 and earlier front cover, 85 and earlier irons (could be 12A or 13B), and a GSL-SE center iron. The GSL-SE engine was something of a preproduction FC, with unused provisions for center engine mounts.

 

for some reason, i guess i never bothered to check back with this thread, so i missed this response. as Crit pointed out, the SE motors had provisions for center mounts. most people miss this fact.

 

^interesting.

and yes it's a 6 port engine.
