[19dart68]

i have a set of heads can someone please help me with the numbers. not sure what they are for. they are early 1970s 3418915 and 2671587 thanks

If I'm not mistaken these probably came off of a 360, are open chambered and sit around 78cc's.

Can somebody confirm?

73-76 340-360 heads on the 587's IIRC
915 are from 70-72 340's and some 360's

first of all thanks for the info, so can i use these heads as a set or no? they would be put on a stock 1971 340.

Both heads are 65-73 cc's according to my Mopar book as long as they both have the same size valves they can be used together no problem..
