I'm putting together two gen 6 502s they came with 14096188 casting # heads are these decent heads for these motors? Two are cracked so trying to decide wether to find two or switch all 4? Thanks

I'm using srp 139483 pistons

Those are the open chamber LS 6 heads so they should be good cylinder heads.

Check if they work for Gen 6 - I am not sure

gen 6 blocks are fine with the right gasket. a few gen 5's had very little meat around one cooling hole in the mark 4 head and were questionable.

Pair for sale in swap.
