Hello from San Diego,
I did a deal on quite a few 427 parts a few weeks ago and ended up with three single 427 heads! I am looking to match up these heads if I can. I have one Hi-rise head, one Mid-rise head and one Tunnel Port head.. Dates are not that important to me on this! Also, my TP head has been shaved down near the end of the thumb print, so... if your spare is like this, perfect. Will want your head to be magged! Complete or bare doesn't matter to me. If this applies, get in touch with me.
Mike
