I wasn't aware that Offy ever made a large port 409 intake,small port, yes.
I have one of those "tall" Offys and it is small-port. Pretty sure Don is right.
Sorry about any confusion.... I assumed..... and we all know what that happens then ..... I didn’t know what offy had offered..... by reading the caption under the pictures it states high and low rise.....I thought they meant high and low performance.... my bad .......It’s still appears to be an offy

No confusion here Keith.Offy made several types of manifolds and might have made some large port stuff .I've never heard of one,but that's just me.I'd be like Dave,it's got small port heads until proven otherwise.

I enlarged the photo to look at the location of the bolt between the intake runners to see if it was a drilled hole like small port or the notch like the big ports. I am pretty sure it is small port.
