I know they aren't in great detail, but those are the three best ones I can come up with now. That was my second attempt at some homeporting and it seems to have come out pretty well.

Be careful in the exhaust bowl area or you'll port into the water jacket and end up removing your new engine to take the head off because heads studs will prevent you from doing it in the car. Don't ask me how I know:o

thanks thats awesome. did you ever have those flowed? also did you grind the exhuast guide completely flat? :eek: ive never seen one done like that. is that common? im keeping mine on a mild port, clean everything up, smooth the guides and try to help with what i think the "flow" would like to do.

Here's a few shots of what's on my LT1 TA. Sorry but the camera was a serious POS, LOL.

Thanks! I did have the heads flowed.

Intake flowed 243 cfm @ .550 and 242.9 cfm @.600. This was with a 2.00" Manley RaceFlo valve, before a competition valve job.

Exhaust flowed right at 180 @.600. This was with a stock exhaust valve, before a competition valve job and back cut on the valve.

Not exactly scorching hot numbers, but considering the work was free and I got some pretty decent mid lift numbers out of the heads I'm happy. I just can't wait to see how the new combo works out.

here's a few of mine. first attempt. they came out pretty good. bout the same as the other fella's as far as flow goes. but I had stock valves. later I did smooth off the valves a little on a bench grinder. just took off the edge or "hump" the air would have to flow over to get into the cyl.s at low lift especially. but stayed away from the seat. but I wish I could have just bought some good aftermarket valves. not enough funds at the time though. next set I do for my Z will have aftermarket valves in them forsure.

actually a much better pic of after I finished them. the other pic was not quite finished yet.

I was fortunate enough to get some time on the flowbench. The guys at the machine shop really did help me every step of the way. The owner got my head on his flow bench, and I was able to get some back to back comparison between the stock valves and Manley RaceFlos. Verdict- the 2.00" Manley intake valve flowed better than the stocker at all lift points, and the stock exhaust valve flowed better than the 1.56" Manley valve.

Re: pics of chambers and bowl area
 

cool. remember how much better the intake valve flowed? wonder how the stock exh. valve could have poss. flowed better then the manley valve? also Ive heard a multiangle valve job does wonders for low lift numbers. I used a drill and lapping compound to clean off the faces of my valves and seats. seemed to clean up really good, but there is only like 2 angles there if I remember right.

Re: pics of chambers and bowl area
 

The Manley intake valve flowed 4-5 cfm better than the stocker did at most. I think the deal with the exhaust valve is that with the stock one being smaller it shrouded less in the chamber.

Here are a couple of pics of my home port, an "almost finished" port shot and a final shot of the bowls. These peaked at 249cfm @.550, a decent improvement considering only about 2-3cc of material has been removed from total port volume. I think you will get a little more flow by raising the roofs, but I pretty much left them alone.
