I recently got a 96 gsr that is supposed to have quite a bit of mods on it. I plan to go get it tuned pretty soon but want to be sure they parts are there that are supposed to be. to do so i plan to pull the head and check out as much as i can. the things i really dont know what to look for to see if there what there supposed to be are:

Golden Eagle Iron Sleeved GSR Block
40 over je piston
head is races ported and polished
Eagle Rods
ARP Rod Bolts
ARP Head Studs
skunk 2 stage 2 Cams
Skunk2 Adjustable Cam Gears
skunk 2 valve springs
skunk 2 Titanium Retainers
Portflow Valve Seals

could anyone give me a way to find out?????
