Ok have done some extensive searching (i mean extensive), and this is the dilemma:
- there are no aftermarket cams to suit quad avcs gt liberty \ legacy heads
i can find dual avcs aftermarket cams by the following makes:
- brian crower
- kelford
- gsc
- tomei
- cosworth
- hks (seem to be discontinued)
the above however seem only to cover v7/8 sti 2 litres, which are not quad avcs (intake only); also the above are made for quad avcs ej255 and ej257.
Dilemma is finding cams for our ej20Y motors ?
Has anyone tried regrinds before? If not what are people using?
