Nice , i might consider those also

 

I think that price is for one head only.

 

We noticed that.

Price not withstanding... I'd pay it.

 

So is anyone running them???

And what do you guys think about these heads vs. AFR lt4 cnc heads?? Anyone know what the lt4 AFR heads flow??

 

wtf?
you can get stock castings to out flow that. Flow isn't the end all but those are some downright embarassing numbers for comparitive purposed.

I promised seth i wouldn't post my flow numbers, but i can tell you right now LT1 castings outflow those on both intake, exhaust and it looks like midrange.

 

youre insane

you can get bare LT4 heads for under $1k..........then get a MUCH better port job for less money, with larger valves.



trey, keep in mind those flow numbers are using stock valves, are yours larger?
also, its a CNC port job.......not a hand port.........CNC is for consistency, not to be the best hands down.

 

Watchword is...always have your heads flowed at a competent, NEUTRAL shop. Then...and only then, can we talk numbers. Too many ways to skin a cat to always believe what you hear.

 

who cares what it is for $2200

 

Thank You.

As much as i love the LT4 Heads.. I don't know if i'm willing to pay 1100 Dollars for the Ported Ones.
