Quick Question

I ordered a rebuild kit from Summit and got 2 diffeerent types of valve seals 8 black ones with 2 metal rings and 8 blue ones with 1 metal ring and an expander ring clamp deal. Which is for the intake and which is for the exhaust???? BTW i have Windsor JR.s i think theyre called but in Summit theyre called Windsor R 180s. Please help Im waiting so i can put my heads together Thanks

HAHA actually i tried that but the guys the 2 guys i talked to were clueless and he asked a bunch other guys and he said " Our estimated opinions is that the black is for the exhaust (has to be high temp seal) and blue is for intake" or something like that but i wanted to ask u guys next since im sure u have done it more than them since we all got stangs.
