lets play, name these heads

( I know this should be under talk, but I thought I would have better luck here. )




I was told there windsor SR heads. But they have J/R stamped the right side above the valve spring. So I'm assuming there JR's and that there world's heads. Can anyone help me out identifing these heads?

Thanks

Look for a part number and google it! That's how I got the info on my heads...

Yep SR is senior JR is junior, should be a W on the front of the head also.

Thanks for the reply. I couldn't find ANY letters, numbers on these heads other than J/R

we must have the same heads because mine has the same letters, I just tell people they're World's Windsor Jr.'s, they looked Identical to the ones in Summit so I would say they are.
