IO 390 engine mounts ?

Hi , Pardon my ignorance but, is a engine mount for a angle valve IO 390 the same or different to a parallel valve IO 360 (180hp) & would the IO 360 fit in the same cowl ? Regards .
I’m looking at changing a IO 390 for a IO 360 in a not yet flying aircraft !

Yes probably the same, Dynafocal #1

Can confirm. I replaced a parallel valve IO-360 with a IO-390 on a flying 7A. Same motor mount and cowl.
