I just bought these a few weeks ago but decided to take a different route. They are brand new in box. They flow 297cfm @.600"

$900 + shipping

 

will they work on an lt1?

 

For another $400 or so they will

 

I think they are worth every penny to convert. Especially because you can use the single plane intake with them without converting. I chose the Accel Pro Ram EFI intake. $495 at Summit. Lets say that you spent $900 on the heads and $400 for modifying to the LT1. Thats $1300 for a set of 297cfm @ .600" heads. Thats awesome.

However, I did decide to keep these heads. You can order some from Chris @ kyspeedparts for $930 shipped.
