351 Windsor head info needed
Fairly new to this but need some help working out my heads.
I live in Australia and have a set of reconditioned C9OE 351 windsor heads,the confusing part is they have 1.45 and 1.78 valves and all I have read says they should have bigger ones, maybe this was just an Aussie thing as the 351 windsor only came out here for a couple of years before we switched to the Cleveland.
Also they have 3/8 press in rocker studs with 5/16 threads,what rockers do I need without machining the heads.
They are going on a 302,there seems to be a heap of conflicting info on what needs to be done to fit these I have the steam holes and dfferent head stud thing worked out but pushrods are still the big question,what length do I need ?
Any help will be apprieciated as its hard to try and get this info.
