I have a set of 5.3 head's off of a 99' silverado I just put a head's and cam package on..they are stock to the bone and have 37,000 miles on them...Better than 5.7 LS1 head's due to smaller combustion chamber..same port design as 5.7 head just with smaller chamber and smaller valves...but I have a set of 2.02/1.575 stainless manley pro-flow valves for sale that go in the LS1/LM7/LQ9 heads..also 918 blue stripe springs with retainer's and locators...all items are BRAND NEW excluding the head's of course...

Or I can fully do them up..install the 2.02/1.575 valves,spring's,retainer's,full competition porting of intake and exhaust runner's,3 angle comp valve job,re-surface to desired compression,new valve seal's,bead blast, and flow sheet included for $975.00 complete with no core charge!!

Thank's
