408 cam / build help.

Next winter or if you are as I it would be had hoped and last winter :)

used 2.02 J heads you have to watch for recession and all the previous history
I'd rather get the smaller valve heads and put in new valves myself which gives me new seats on the intakes
you can check the installed heights to see if they are all over the place and if so pass
as said do not dump a bunch of money in worn out Iron unless you are restoreing
