I6 223 head/intake question

I usually hang out in the 57-60 pages and was hoping someone over here can shed some light.

I have 1960 223ci in a F100 that I want to add an Offy intake with two single barrel holly carbs. Offy intake says it will fit 57-59 223. Only difference from 57-59 and the 1960 that I'm aware of is the valve cover on 57-59 has two bolts in top and 1960 valve cover has 8 bolts around edge.

I've been informed the 223 heads are interchangeable from a wide range of years from 53-64 at least.

My question is will a 57-59 intake fit on a 60 head? If yes why does offy intake say 57-59?

Any info anybody has would be appreciated.

To my knowledge all years intake interchange. Sometime around '60 a PCV type system was introduced which was plumbed into the intake. Maybe that is the difference.

I still have road draft tube. So PCV must be after 1960 or maybe a custom cab version of the 223.

I'm hearing something about the bolts that mount intake are longer for 57-59 and shorter for 60. 60 intake being shorter

I did call and tech guy wasn't there. Supposed to call me Monday.

I think the flange on the 60 intake is thinner and mounting studs are shorter that 57-59.
