RGR heads, are they any good?
I've seen M6 cars dyno 420rwhp or more with them and a cam.
I've seen an A4 car dyno 405rwhp UNLOCKED with them.
All the cars with the heads have performed well at the track as well.
However, if your in the $1700 to $1800 price range, you might want to look at a set of TEA Stage 2 heads. Dual springs and lot's of good stuff for $1800 if they are not on sale. On sale or group purchase and for less than $1600 you can get a set of heads that have made as much as 440rwhp.
The TEA 5.3's seem to be the hot ticket.
