For sale is a pair of professionally rebuilt LS heads, casting number 243.
These originally came off of a 2009 GMC Sierra with a 5.3.
They have the updated and improved copper sintered valve seats.

The following have been completed:

*Heads were disassembled, cleaned, and pressure tested for cracks.
*All bolt holes were inspected, chased, and repaired as needed.
*All valves, guides, seats, springs, keepers, and retainers were checked and reconditioned or replaced as needed.
*All new bronze valve guides were installed and honed to size.
*The valve seats were cut using our Rottler SG7 seat and guide machine with a performance 5 angle seat profile
on the intakes and radius profile on the exhaust side.
*Heads were milled ~.010".
*Heads were assembled with new valve stem seals and new GM blue springs (12499224) with a max valve lift of
.550".

We are asking $1015.00. This does include a $300 core charge. Call us if you have similar cores (Casting # 243 or 799) to exchange. Also we will accept other LS heads as cores, but the value will vary based upon casting number.
