			Thunder V12 has valve springs listed for sale.  I assume these are for V12 engines which I think are non magnum. Would anybody know if they are the same as used on a 401 Magnum motor?    Thanks in advance Dave

			You got me, but I think there is a valve spring for engines that do not have valve rotators  and one for engines that do.  About the only V-6's that didn't have rotators were some light duty 305's in pickups.  Did the seller give a part number?
