I was thinking about buying a set of there stage two 4v heads but there kinda pricey($2695) does any one have good or bad info on them? here is the info off there page

• Current production 4.6L DOHC 4V aluminum heads
• Fully ported and polished with advanced port shaping and combustion chamber
unshrouding give these heads the edge for all out street/race use
• Can be used with stock cams, but will perform to its max when used with SHM performance
grinds
• Fully machined and assembled using SHM exclusive stainless valves, hardened retainers, and
single groove keepers
• 52cc chamber volume

They also have ported lower intakes for $895 again kinda pricey any one have good or bad info? here is the info off there page.

Ported lower intake for 99-01 Cobra, Mach 1. We cut the
bottom off the plenum, allowing us to access the inside of
the intake. Then we port the intake from the inside, and tig
weld the intake back together. Provides a 20% increase in
airflow.
