I could afford no more than $1500 for a set of cnc's. I know the edelbrock type aftermarket heads for domestics tend to run around $750 to $1500 a set. If we could get a similar deal I would seriously consider a set.
$3600 is the cost for bare heads. it doesn't matter what port job you get.
There is a customer who has a set on a JZA80 Supra plus he has some 270/280deg cams in it also. But he's running the stock intake for now as he might go supercharger. but i'll post up the results either way. I'll be trying to do back to back runs with the billet intake on that car.
The 2mm os version is going on a 4.8L I'm also building but again no before and after just the whole build. That one will rev out to 10k. The heads all up are about 12 i think.
