Default Gen IV 6.0 and Gen III heads?

Picked up an LY6 Gen IV 6.0 short block (just the block, no heads), and I noticed the pistons are fly cut.

I have a TBSS intake already and for the sake of budget I was planning on running 243 cylinder heads but don't the LS3/L92 cylinder heads that come on them anyway have staggered rocker arms?

Does that mean the valves from cathedral port valves wouldn't line up?

The rockers on the LS3/L92 are staggered because of the valve placement. The 243's will bolt right on with no issue.

the square port heads have large valves that is a reason why they have valve reliefs

running a cathedral port head youll be fine, now if you choose to run a cam like the Trex then youll be fine as well for ptv with having reliefs
