? about heads

[wild1and83fan]

I have a set of heads i got from a friend the cast numbers say 450 on the bottom is this right? are they good heads for a street stock? are they legal? let me know thanks for your help

the number you need to be looking for is on the top where the valves and springs are,find that number and give me the ;last 4 digits and ill tell you what they are and how good they are.

what motor are you running..these arent bad heads,they are off the early 305 and are 60cc chambers so they will up the compression on your motor,especially on a 350...with a good set of springs,valve job,and some undetectable portwork they would work great!

Sorry but you cant run 305 heads on a 350 at TCS or Godfrey. I know , I found out the hard way.....

well there goes that idea wild..anytime you can run 305 heads on a 350 in the stock classes will help greatly if done right,not to mention they work well with the carb rules,too bad you cannot use them..since the rules go that way i would recomend a set of 487
