question about Windsor and windsor Jr. heads
 

Is there a way to identify Windsor or Windsor Jr. heads? I'm thinking about buying a set of windsor Jr. heads from a guy online.
The data that he has provided me with seems incorrect.
He claims they have 2.02/1.60 valves and 64cc chambers.
I thought all Jr.'s had 1.94/1.60 and 58 cc chambers.
Then I though "maybe they are Sr. heads" but I read that the Sr. heads are 69cc chambers.
Is there a serial number of casting number that I can ask from him to make sure there are WORLD WINDSOR heads?

I know he could of had the larger valves installed but the chamber sizes seem off.
He either doesn't know what heads he has for sure or he's trying to pull a scam or possibly I don't have enough info about them as I though I did.

The windsor seniors have 2.02-1.60 valves and 64 cc chambers and they are aluminum heads. the roush 200 heads have 2.02-1.60 valve 64 cc chambers.

It's been 2 years since I put mine on, so I don't remember any numbers, but I do remember that they said JR on the the surface next to the springs. I don't remember exact location but I do recall it being very apparent. You are correct about the valves and 58 cc chambers. Sorry I couldn't provide more info, but hopefully that gives you something to look for.

Actually both Jr. and Sr. can be had in aluminum or iron so don't go by that.

True, the jr's and sr's can both be had in iron or aluminum. The Sr's have 2.02 / 1.6 valves and 64 cc chambers, the Jr's have 1.94 / 1.6 valves and 58 cc chambers. The Roush 200's, of which i have a pair are basically just reworked Sr's. In fact i think it was more of a marketing change (putting Roush's name on them) than it was any drastic rework.
As far as telling the Sr's from the Jr's if they changed the valve size in the Jr's then you'd either have to find a marking on them somewhere or measure the runner volumes ... the Sr intake runner is 200 cc and the Jr is 180 cc exhaust is the same on both.
Good luck :)

I could be smoking crack, but i could have sworn I saw Jr heads with 2.02 valves, orignal

Well not according to World Products. The only difference in the Jr's is slightly smaller intake valve, slightly smaller intake runner and slightly smaller chamber. Then again, maybe i'm smoking crack :p

all windsor jr heads hae 1.94 intake valves, the early ones had 1.50 exhaust valves(i have a set of the early ones) and the later ones have 1.60 exhaust valves. the windsor heads have the 2.02/1.60 valve combo.

I emailed WORLD PRODUCTS and they said it sounds like a set of early heads that they don't make anymore.
