Roller rockers?

[SMOKEDYA]

I have a 351W NONroller motor i have a set of ported polished GT40P heads with cobra 1.6 roller rockers. Will the stock NON ROLLER 351W pushrods work with the roller rockers? peace

It depends what size the button is on the rocker.
The most common pushrod diameter is 5/16" so in this case the pushrod cup or button on the rocker must be sized to accept the 5/16" pushrod ball end.

You should also measure for proper pushrod length.

i took the 351W pushrod to work and mic'd them. but even tho there from a non roller motor i can still use roller rockers tho right. peace

When referring to an engine as a roller motor we are talking about the cam lifters/tappets. This is completely different than the rocker arms. Like 347HO said though, it would be best to use a pushrod length checker to make sure you get the right length pushrods.

I had been thinking about your post.
If you are installing guide plates, you'll need to purchase at the minimum hardened pushrods. I suggest you use chromolly.
