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.
