Default L92's

My L92's flowed 346 (I) and 226 (E) @ .600.

I was there when he flowed them after they were cleaned up.

I'll find my sheet but my ported LS6 heads did less than I expected but the guy doing the work said it was better than he was expecting so I'm not too upset. I think they did 296-298cfm intake at .600. I'll find the sheet and post the numbers.

p.s. These were stock valve TSP ported LS6's.

Go to the pharmacy and get a cc seringe, use that. I used dyno oil, keep the plug in.

Did you tape the runner off on the intake manifold side? At what point on the head do you stop? When the oil hits the bowl area?

Pretty good, Bo did a superb job on them. Considering this is a boost application and on stock valves, also hand ported.
They were very consistant in flow amongst cylinders, ranging from 287 > 293 at .600
Chambers barely touched, and real good bowl and runner work

LOL, I had to to design the cam specs.
The project is not finished yet, so I was waiting to do so for a full write up.
Like I told you before, I wish I had your talent, I'm lucky to own a piece of your art.
