Those aren't correct, those #'s indicate they flow worse than stock peanut ports. I'm betting those are the #'s for SMALL block vortec heads.... those would be much more like what a decent small block head would flow.

Madmax is right, the numbers are likely for small block heads.
The link is good sutphen30, lots of good info, no L-29 heads though.
Donman, you may want to try numbers in between the GM 049 and the WP Merlins.
Are you running numbers for the ZZ502 cam ???
I need to buy that desktop dyno...

Hey DonMan,
Are you going to put bigger valves in those heads?
Post some numbers if you don't mind.

My 454 went kablooey so I`m considering building a 496 shortblock, possibly a 540....
I know these heads aren`t that great, but I already have them and really can`t afford better heads right now. Just hoping to get a little good from them.

Hey DonMan,
Sorry to hear you 454 went boom
sutphen30 posted a link to the flow numbers from high performance chevy.
Would you mind running the numbers for the ZZ502 cam in a 454?
