    PCE281.2165 is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Seem like fine heads, but NOT Ram Air IV exhaust p Ram Air IV had ROUND exhaust ports. These have standard D-shaped exhaust ports. Huge difference. These will be easier to find headers for, but these are NOT Ram Air IV-style heads and won’t flow like them. Otherwise they look like fine heads.
