I bought these heads from GranSportSedan a few years ago and never used them - they flow @280/200 according to what I have - the heads are stage 1 valves, full port work done, polished chambers, new springs, guides, retainers, etc - have all new hardware and are in excellent shape - I will post pictures. $1000.00 shipped to lower 48
I will have to find out from GranSportSedan - I know that these heads once belonged to Gary Payne and were used on his racecar - I also know that GranSportSedan sent them out to have flowbench numbers and some addition port work done to them.
Thanks John, I am still waiting to hear back from Nigel. I am looking at buying his car as well. Thanks Herb

John your up I am in the process of buying Nigel's convertible, so I won't be buying these. Thanks Herb
Since I hadn't heard anything more on this for a week or so it seems, I made some other cylinder head plans. Sorry. Too late! ou:
i may be interested. i just found out that the 430 heads i got had a crack in one of the comb. chambers. i have a guy that is going to give me a quote on doing work on my 70 455 heads. if that is too high, i will talk to you by saturday.
