1st- 3400 heads all have 1.6 rockers stock.
2nd- you'd need custom length pushrods if doing the 3400 topend swap and you should match them to the cam you're using as well.
3rd- as everyone else said, cranks are hardly the weak spot on any of the 60* motors and it would be pointless to swap.

now swapping an entire 3400 is a different story.. you're basically starting from scratch.

Forcedfirebird on 60v6 used gen 2 pushrods with flat tappet and gen 3 heads.

I think it would be best to just do the top swap for now instead of a complete swap.
I'll have more money left over for the body work and suspension
