Default head gasket ?

Anyone know the best head gasket to use on a 454 gen 1V with dart aluminum heads around .040 thick
Usually use fel pro but can't find proper #
Any input would be appreciated

Make sure you put the headgasket on the head first and make sure that the wire ring does not hang over the combustion chamber on the head.

Many aftermarket heads require a 'bigger bore' headgasket than you'd think.

Most don't check against the head, which , again,not doing so is a 'No, No' with todays aftermarket heads as most heads combustion chambers are designed for bigger bore motors.

Mike thanks for the input
That # comes up as the economy gasket
was looking for the best gasket I can get

Dart recommended Fel pro # 1037 But that requires drilling two holes in the bottom of the block for coolant passages, and the two upper side holes are not in the gasket , not sure why? Not too comfortable with doing that.

also forgot to mention this is a 525 sc engine

Every 525 sc I've seen was a gen 5. Good to know on that gasket number.
