273 rocker info please

Guys, what type of issues will i encounter if i use the 273 rockers on my semi stock 340 build?
Will this be a direct bolt in with proper sized pushrods or will i encounter geometry issues, be patient with me please, im learning as i go...Rich
Clearance them for retainer and spring . Same as installing 318 rockers on a 340. They will not fit without hitting. read this and check the area of the arrow
