305/350 Heads

I would like to put a 350 in place of my stock 305 HO in my Camero. Would the heads off of the 305 work on the 350? From what I understand the 305 HO has larger valves. The 350 is out of street-stock racecar that got T-Boned the first race. The heads on this engine would not allow pump gasoline due to too high of compression.
If anyone knows please let me know. Thanks

Need more info, what year engines, casting numbers on engines and heads. And if it was mine id check on gasoline alternatives and do a complete swap to keep the compression if possible.

Really I had a that combo in a 75 vette worked great! But if you going to drive it on the street you need to be able to run on pump gas. I was at 11 and half on my vette could only run pemium.
