This listing is for a pair of used 243 port LS cylinder heads. Cathedral Port

These came factory on the LS2 HSV engines. The Ultimate head if your are chasing throttle response and mid range power gains (power where you use it)

Bigger intake and exhaust ports than a 241 head and smaller combustion chamber to bump up the compression.

These suit all LS engines

These are second hand and would require the usual service/check/machining as you normally would when reusing heads.

They are genuine GM. Inspections/ pickup welcome. We use a generic photo for this listing.
