Intake manifold gasket installation help

The intake does have the relief around the bolt holes. Starting to believe these are not the right gaskets to use. The engine gasket set is Fel-Pro FS 8553 PT-10. I looked it up and shows Plymouth Barracuda '68 to '73. Don't know why the rebuilder used this set. I'm going to order the Fel-Pro MS9935 intake set as shown on Rock Auto's site, and not use these. Evidently the lower end gaskets are the same but not the intake gaskets. I had a bad feeling about these, thanks for pointing out the fit issue, these are for a 340 or 360 it seems. I have stock 273 heads ending in 315.
