This is a question that has an answer

The Vortec is a far better head. The 12480034 head is intended for racing classes that require a "Stock/Replacement" type head and they're based on the '462 (camel back) type casting...but with a ton of extra room in the casting for decking or angle milling and porting. They have a bit better chamber and runner configuration than the old heads, but not by much. They're only available bare for around $750/pair...so they're pretty pricey for mild street head!

This is the same type of head offered by Dart, World, etc. that has been certified for those "old skool" racing classes.

Racers add in 40 hours or so of porting and maybe a little angle milling and get a pretty decent tier 1 head out of them...but for most folks either the Vortec or another tier 1 head is going to be a better deal.

ok sweet thats some good info!

I was mainly asking what the difference between the two was. not really trying to compare. my bad!

So these "vortec bowtie" heads, are they good for the street or more for race?
