so I bought some 1.7 rocker arms for my 2.0 rebuild.Many blogs say to us swivel feet for many reasons.I just want to know what length of push rods to use when doing this modification?? this will have stock stroke.I think this matters?? not certain? its a 76 2.0 that I am rebuilding and the rocker arm modification is complete so now for the push rods? of course any other relevant knowledge is appreciated!!
Oh yeah and anybody know the stock ratio of these stock 1.7 rocker arms??

No set length. Each engine will be different. Google "valve train geometry" then spend hours reading.

looks like good info

The stock rocker ratio is "notionally 1.3:1". They're not all super consistent, and we have seen ones that are 1.3:1 and some that are 1.4:1 .
