I'm about to purchase a newer roller 351 Windsor from 1993 and up, I'm just wondering what size valves come in the heads and if they are just the same heads as the ones on the explorer motors...GT40P's???
They should be the same E7 head that come on the mustangs of that era. Post the part number if you can.Unless it was a lightning motor than it would have cast iron gt40 heads.I think those had 1.84 in and 1.54 ex valves. Gt40's are much better than the E7's.
