I want a nice set of LT1 heads. May consider trading my LE heads towards a set or I might put them on another one of my LT1's. Anyway, heads must be:

at least 210cc intake runners
2.02/1.6 or larger valves
aluminum, angle plug
std exhaust location
either centerbolt or perimeter bolt valve covers
flow over 300/200 cfm @ .600 lift, more the better
accept standard 23* hardware with std port locations
between 58 and 66cc's (ideal is 60cc)

These are going on an LT1 with a single plane with a std sbc bolt pattern. I will have the coolant ports welded and the heads converted unless they start as LT1 heads. Either way I have to convert the heads. Must have flow numbers/chart capable of supporting 550RWHP in a 388ci motor. It would be easiest to do this by someone looking for a decent set of heads for trade since I have to get rid of my 277/198 LE heads to get a really spiffy set. My heads wont come off the car for 2 more months since Im deployed, however.
