Hey Charlie....I have a set of o-dash alum heads that are dated 63(if I remember correctly)...its been a while since ive actually looked at them...are the outer exhaust port header bolt holes angled at 45 degrees...mine are...I definitely will need custom headers made if I use these heads...Im curious if yours are the same and the dates?? aI have an article from Hot Rod stating they were nascar heads, but Id like to know some more history on my heads...anyone???
BTW I dont like this stuff...I ADORE this stuff ...too cool!!!
