piston question

i have 460 with c9ve heads lw2602 flat tops with 1 valve relief is the relief cut for the ex valve or intake valve cam size 543L 574ex thanks guys

Generally Big Block Fords only require an intake valve relief.

If your pistons only have one its for the intake.

thanks man got short block together was throwing me off because #s on pistons are up side done when in the hole put thats where it needs to be for the intake valve thanks
