Noob, w/ ported head stuff inside. Hello, I just signed up today so I guess I'm a noob. I currently have an 84 SVO and an 85 Turbo Coupe, but a lot of friends have LS cars and I am a big fan of these engines.
Anyways I have been porting heads [many different kinds] for a while and I recently did my first set of LS1 heads for someone and paid to have an intake and ex runner flowed. They were 6.0L "317" truck heads here are some before numbers I found online of the exact casting... dumbass I am... should have flowed them before, the guy didn't seem all that interested in doing that, till they were done...

I'm just wondering how I did.. you can't see from the angle of the pics, but I did make a hole [and removed a lot] where the rocker bolt boss was.. I made a plug for the hole and then blended it, and had him flow test it w/o the plug and with.. and the difference was NIL....
Just wondered how these numbers looked, Thanks.
