MMR stage 3 ported Romeo PI heads. They have a set of custom Bullet racing cams. See picture for specs. Also Crower high lift springs and retainers. The heads were given steel timeserts for the plugs for added boost protection. The whole thing has about 8K miles on it. But we're inspected after removal. One picture shows the receipt after removal. They need nothing and are ready to be bolted on. Not interested in any trades. SOLD! The cam gears are no longer available. So I lowered the price.
