Roller Rocker Issue

[jesseromero]

I recently put 351heads on my 302 block and came to discover that the 1.7 roller rockers don't fit. 1.7 roller rocker stud to install the roller rockers was to skinny for the hole in the 351 heads???
Can anyone help?

What 351 heads did you put on? Do you have pedestal (OE) style rockers? If not, what style rockers are they? Got any pics of the issue?

We can help more with more info.

Sounds like your 3/8" rocker studs are too small for the larger 7/16" holes in the 351 heads. I'm not sure if you can get your rockers to fit larger studs, you may need new rockers or some kind of adapter stud.
