Restoring a 340 need advice

First off... Noticed you joined today .Welcome to FABO!!

Lots of great info and good people on here!

My input.. Get the valve seats hardened for unleaded fuel while the heads are off. Cheap insurance and not costly to do. Keep the LD-340 intake, one of the best Mopar intakes ever made. I agree with the above posts, Keep the factory valvetrain. Cam choice will depend on converter /rear end gears/tire size as was stated previously. Headers will work wonders!

Keep us posted on your progress!!
Thanks. while disassembling the heads i noticed the seats were already changed for unleaded, also looked as some of the valve guides were sleeved. the valve job was def not done very nicely as the heights are not even at all. we will be making the seats all the same height. i do want a full new exhaust on it. I know its easier to keep the oe valvetrain but i want better haha. I just want it very smooth running without having issues down the road
