STI RA v3 or 4 HEADS
Hi,
I'm looking for a pair of STI RA v3 or v4 heads, complete, in excellent condition.
The RA heads have the most agressive cam profiles available, and are good for revving up to 8000+ with good flow characteristics.

Version 3 Sti heads have a more agressive cam compared to the Version 4 Sti heads, but I don't know if this would be the same for the RA heads.
I would image they would be, so I'd so go for a set of STi version 3 heads.
If its for a big engine build, it doesn't matter any way, as I'm sure you'd stick a diffenet set of cams in they while you're having the heads polished and gas flowd ha ha ha
