heads and cam -opinions and help ? Scoggin-Dickey have 2002 CNC ported LS6 heads which have been milled 0.055". They come with '02 lightweight valves and '02 springs. Also available is the "Grand Am" cam, 239/251 @ 0.050, 0.570 lift and 106 LSA (Asymmetrical lobes). GM recommends the 2002-03 LS6 valves and springs with this cam. I want to put these on/in a 2001 LS6.
1. Will I have adequate PTV clearance( since they were milled 0.055")?
2.Whose springs should I upgrade to?
3. 7.350 pushrods?
Any and all suggestions would be greatly appreciated !Thanks! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
