will a itr valve train fit in a b16 head without changing anything and if i put ctr pistons on gsr rods and use a b16 head will everything work fine or will i have to change something

 

im not 100% sure but i think the gsr rods stroke is longer than a b16's

 

i have a gsr block with a b16 head does that make a difference

 

big difference, you should be fine tho

 

ok so everything should be fine with the pistons and rods how about the itr valves and springs

 

everything will work piston wise as long as you havnt shaved or decked the piss out of the block/head

and the itr valvetrain will work with no problem along with valves, i would recommend getting a machine shop to recut the valves and doing stem seals
