'70 340 O Cylinder Heads Mopar Cuda,challenger 3418915 Same Cast #s As Aar T/a on 2040-parts.com

THIS IS A VERY NICE SET OF (O) MOPAR SMALL BLOCK 340 SAME CASTING NUMBER 3418915 T/A AND AAR HEADS THEY DONT HAVE THE OFFSET PUSH ROD HOLES . THE CASTING DATES ARE 1 DAY APART LATE 69  1 HEAD IS 10299 THE OTHER IS 10309. THEY HAVE BEEN MAGGED AND CHECKED AND YES THEY ARE THE 2.02 INTAKE VALVES SEE PICS AND THE 1.6 EXHAUST THEY HAVE NEVER BEEN MILLED OR PORTED THEY WILL NEED A VALVE JOB . I WOULD RECOMEND HAVING THE EHAUST HARDENED SEATS INSTALLED FOR THE UNLEADED GAS IF YOU TAKE TO LOCAL MACHINE SHOP THEY CAN SET UP IN MILL AND MILL THE PUSH ROD HOLE OVER FOR THE OFFSET ROCKER THESE ARE VERY NICE CLEAN HEADS MAGGED CLEANED I HAVE PAPER WORK COMES WITH ALL VALLVES AND RETAINERS AND LOCKS I ALSO HAVE THE STOCK SPRING IF YOU WANT  THEM. BUT I WOULD PUT NEW ON TO FIND A PAIR WITH THIS CLOSE OF DATE CODED HEADS WOULD BE VERY HARD SO IF YOU HAVE A 1970 CAR THIS IS THE TICKET , ALSO THESE ARE THE SAME CASTINGS AS THE J/U/Z HEADS BUT WHAT MAKES THEM 1970S IS THE DATE CODE. IF HAVE QUESTIONS PLEASE ASK THANKS CRAIG 419-989-5027

I WILL SPRAY DOWN WITH WD-40 TO KEEP FROM RUSTING BECAUSE THEY ARE BARE METAL THANKS AGAIN
