You could also have them hand ported instead of a one size fits all cnc port job.
I know cnc is the trend nowadays but just something to think about...!

Thanks!I was thinking more on the hand porting and that is from a cost factor for now.

I measured the bolt hole depth and I will be able to use the studs I have in there.SWEET!

I got the heads flowed.This is OOTB!

That exhaust is going to need some work

Hope to see these perform next year

Are those CFM measurements at .100 to .800 valve lift?

I was curious as to which numbers meant which numbers I'm assuming the second row is thw adapter use to flow at those numbers and the second line is the results in CFM, yes? Also what are the top numbers ?

Look like port dimensions to me

I am watching this one! Are those the standard 77929 Victors out of the box? Mine started out as the standard port but were ported to MW size..I am thinking I went overkill on this!!

the heads are 77929.
1st # lift,2nd is flow range,3rd is flow in that range and last is calculated flow.

Thanks! Now I know I screwed up...Should have just did the essentials and saved a buttload of money...

Those #s look higher on the intake and lower on the exhaust than I've seen for other OOB 77929 heads, so I'm not sure how comparable they are to the rest of the data I've seen for that model of head.

In the long run they are just #'s to start with and a big improvement over my iron heads and for me a very big move to make that I have waited to do for a long time so I am happy to say the least.

Clanton,

So you are Boosting the motor? Try to raise the mid to upper lifts, the intake needs volume more than raw CFM and great exhaust efficiency is also important; that's what makes the Indy-1 with it's big Intake port and excellent raised exhaust a real natural for blower apps. You want to improve the exhaust to intake bias % since getting air IN is not an issue with boost, and for the powerband you're looking at...you don't want or need a ton of RPM since your torque band is going to be EPIC and roots blower efficency drops (heat) and tends to act as a big brake on the crank past its designed flow rate. Good heads and a relatively slow blower ratio really works great....if you get the cam and timing right it's almost unbeatable and VERY RELIABLE.

I have the Chaoman stage VI's and the most impressive/important numbers are the mid lifts. Basically if you get your .400-.500 OOTB lift numbers to where your OOTB .500-.600 numbers are now and IMO you're all set. beyond that with the blower you just let the peak fall where they may beyond that. Cam selection will be critical, how big is the blower and what CID and static CR are you at. JE makes a nice blower/nitrous dish design. Run as long a rod as possible

Yes the engine has a roots blower/carbs.The casting is rough around the valves and will improve a bunch in the low/mid range cleaning the chamber up and throat.The test bore size will help/hurt flow also so maybe it was done with a larger bore tube.The engine is a 446 3.75 stroke,9.4cr with the heads haveing a choke of 3.14sq.in. with 6800 rpm,.630/112lsa cam so I am sure my port air speed will be fine.

Look at the advertised flow here.

and mine is not that far off.
