1967 915 heads any good?

I have them on my 440. It's a stock 70"s bottom end with headers, purple shaft hemi grind cam, headers, holley steet dominator and 750 vacuum secondary. I bought my heads from a guy who was putting indy's on his engine and gave me a sweet deal. For 800 bucks I got a set of fresh redone 915's with brand new valve spings, with oversized ss milodon valves (214 - 181) installed and mild ported. For my budget these are about the best I could have gotten. Sure if I had loads of money I'd buy better, but this set of heads work real well. With the compression boost and pretty good flow with larger valves and a street car I think they are perfect set of heads for us budget folk. I have not run my car at the strip yet but it hauls *** on the street. Right now up on stands gettin rear spring locate, tub and 4.10 spool.
