What I've surmised that if a car was assembled in Cal but intended for sale elsewere the heads were drilled, tapped and plugged, it will also have the tall oil filer tube. No other hardware present. If the Starfire has the mounting bracket for the reactor pump I'm sure it was originally equipped with the full system. I have 2 '66's that were assembled in Cal and they both have the K19 delete consisting of drilled, tapped and plugged heads and the tall oil filler tube. All my other '66's were built in Lansing are not tapped and drilled and carry the short oil filler tube. My '67 CHP 88 built in Lansing had the full Cal smog system as did any Olds sold in Cal. for '66 or '67. My thanks to Curt A. of Minn. who clarified for this for me a few years ago. Henry.
