pontiac (434) heads

[bigsteve27537]

What all did the nascar teams do to these heads when they ran them. How much poser can these heads make on a 434 ci motor on alc.

I too would like too know more about his head. I have been told it has a 15 degree valve angle. I know where a set can be had cheap with a intake too match. I would like too hear the opinions and comments on this head before I decide too buy them. What is the true potential/limitations of the head, like min/max cubic inch, Flow potential experiences, recommend valve/bore sizes, etc.

Thanks for any input you can provide
