Head numbers

Per an Article from the "Source" news letter, they found that untouched head's flow pretty much stalls out around 150 CFM and .300" lift on the intake. At .45" lift they only flow around 154 CFM (any more lift that this is doesn't matter because our cams don't go that high). On the exhaust side, they flow about 108 CFM at .400".

Alright I just picked up my heads from the machine shop and these are the flow numbers I got.

@.100 Int. 55 Ex. 50
@.200 Int. 114 Ex. 97
@.300 Int. 157 Ex. 130
@.400 Int. 164 Ex. 138
@.500 Int. 170 Ex. 142


So let me hear it, is this a good port job or did I just do a mediocre job?

Anybody?

Personally, I think it looks pretty good.

Are these the results from a simple port and polish? Been thinking about trying my hand at a little porting...

...but what do I know...I can't even TUNE my car!!!!

This was just a home port job. By the way I just moved here from Junction City, KS.

You probably know a few of our KC guys then, huh?

 

[BLACK Ttype]

No not really, I moved away from there about 9 mo. ago. Had the car for less than a year there. Didn't find out about this board while I was there.

Anyone else have any opinions on these flow numbers?

 

[BLACK Ttype]

Your numbers look similar to the 25" numbers I got.

Corrected to 28" they are a little lower.
