Thanks for the replies...I thought that I should be okay but wanted a few opinions first. I already pulled the valve covers to see what heads were on it and I plan on oiling everything first. My dad bought the car from a consignment shop in Michigan back in 1999 on a lunch break from work(mom was not too happy). We were told it was a 427/435 at the time but never really looked into it. Motor is a counter exchange.Stamp pad is CE971xxx. Heads are stamped 3919840 HI PERF. I am in process of removing all fake braided hose/wire junk and will be replacing with factory correct parts. Going with some Cragars and ProTracs once it is up and running.
