Thanks I looked last night at A Bodies site and saw every few years one came up for sale.
So looks like someone woukd need it.
I also got my gaskets out and saw the same. It would be best on a 318 small port head. But bet it would seal with good gaskets on 340 360 heads.
I haved gotten rid of all the 318 I ever had and have no plans of ever using one with 3 340s.
I should have pulled the 273 HP I found at the U Pull it. Was the solid lifter 4bbl one. But was very slugged up. So I just said can't save um all.
I even saw where one for sale had the bolt holes made oval so it would fit. Must have been due to improper deck hight.
So back to wall art or sell I guess.
