I bought the valves here in the classifieds, brand new.
Exhaust are from SI, no idea what brand the intakes are.
All 4 exhaust are 36mm (stock size)
2 intakes are 42mm (stock size)
2 intakes are 44mm (2mm oversize)
Options are to have the 2 intakes turned down to stock or buy 2 new 42mm or go big and buy 2 new 44mm valves
Double springs, retainers and keepers are brand new from European Motorworks.
$160 shipped in the USA via USPS
