These are some more pics of me working and porting on the heads. because of the results I have been porting LS3 heads as fast as I can.
Porting heads
Cutting custom valve guides for heads
Porting intake ports
Milling the heads down to 64.5cc chamber volume.
Reaming and sizing the valve guides
Reaming the guide with a custom carbide reamer that takes them to within .0005 of finish size with an accuracy of +-.00005. They are expensive but well worth it when your doing 120 guides in a day.
Another shot of reaming the guides.
