L.A 360..Magnum ?

Also pre 73 heads do not have hardened exhaust valve seats for unleaded fuels. More cost on te old heads. Tons of new replacement Magnum heads available cheap. Most have thicker decks to help eliminate cracking.

He already has an LA 360 & heads Magnum heads as well also have induction hardened seats snd they suck and crack still... so either set of heads should get a set of hard seats if that's the idea. You arent saving... you re actually going out of your way to spend more to have a iron mag head pos 'that by the time you've swiped the credit card... you could bought aluminum heads and been ahead in weight and flow' .

Never get caught up in head preference.
Weigh the return vs cost and know your power goals.Going out of your way to spend just to run some mediocre production..all cuz you love it so much. Lol expect disappointment.
