Just got them back from the machine shop, had them do a valvejob, resurface the heads just enough to get them cleaned up and glassbead them. Tell me what you think
http://mywebpages.comcast.net/jsbird98/6.0heads
I was told they flow 300@.600in and 250@.600ex. I cannot verify these numbers because I wasn't sent a flow chart with the heads and my machineshop is having a piece made to flow these heads on their bench.
Should I step up to a SS exhaust valve, I was told I would burn mine up if I left them stock.
Thanks,
J

J- deffinatly go with a stanless ex valve, and the only other thing you should do is have the chambers polished, the 6.0l 317 castings are sand casted, the rough finish will cause hot spots and aid in detonation, if you would like to get them flowed, give us a call we will help you out
