Ported LT1 Heads!! GREAT DEAL!!
Ported LT1 Heads!! GREAT DEAL!!
I have a set of ported lt1 heads, factory casting with PAC-918 springs, and titanium locks and retainers, along with ARP rocker arm studs and Ferrea valves. I have flow sheets from GRE Race Engines, they are 55cc, flow about 250 cfm. Great for a stock shortblock or something with a hotcam. I'm looking to get $800 shipped or best offer.






Re: Ported LT1 Heads!! GREAT DEAL!!
please post the flow sheet and any specs you know:
spring installed height / seat pressure
coil bind height / open pressure
how much use on springs? valves?
since valve job was done?
new or knurled guides?
3/8 or 7/16 studs?
this would save being asked a dozen times
Plus, I want this info! Sent pm on other board..
thanks

Re: Ported LT1 Heads!! GREAT DEAL!!
I never ran these heads on my car but according to the guy that I bought them from, they have approximately 1,000 miles of run time since all the work was completed.
