Ported 853 Heads With 921 Spring Kit Hand ported and 3 angle valve job set of 853 heads milled .030. These come with Comp LS1 26921 Spring Kit (used)- Dual Springs with spring seats, titanium retainers, and steel jacketed valve seals. These are race quality springs designed to handle up to .650'' lift.
The spring set new from Comp is $579 before shipping.
We also have a brand new set of Comp 918s that can be installed with stock retainers, keepers and seals for the same price.
Will sell these for $850.00 shipped. These heads are good for a minimum of 25 RWHP to the tire, and as high as 40 depending on the application. Will sell for $650.00 shipped if want bare.
We do not have flow #'s but CC'd the heads last night:
Compression Chamber: 64 cc
Exhaust Port: 82 cc
Intake Port: 213 cc

Great set of heads for an LS1 car as a very cost effective upgrade over stock. Our 241's went out Friday, these heads still need a good home.
