Re: 1.6 roller rockers
You will HAVE to use lock-nuts rather than the stock rocker nuts and you will HAVE to use Valve Covers that will fit over the Rockers / Poly-Locks.
As long as you buy the correct rocker arms, you should not HAVE to replace anything else or HAVE modify anything else to install them on a stock SBC 5.7. ( If you are building an engine - there's more to it then just buying "bolt on" rockers. )
You should gain a couple HP - don't expect to feel it.
