Hello everyone,

Just working on some hedders for a 72ish 500 and was wondering if anyone has a set of 902 heads on a bench or on a stand that they could measure the exhaust port size for me?

It would be greatly appreciated. Actually, I assume the 950 or 250 heads would be the same. BUT, please note the casting number with your measurements - I'd be curious.

Cheers,
bovey

I would think that the size would be the same for the other numbered heads. An exhaust gasket should give you the port outline. Is the 902 supposed to be different than say a 552 etc??
