MY v tec WON'T OPEN?????? HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have extensive work done to my engine it's a 95 gsr engine
block:
jdm type-r pistons
shot peened rods
polished and cut crankshaft
type-r oil pump and water pump
block guard
arp head and rod studs
head:
polished head
type-r valve train
aem cam gears
gsr cams

I hAve tryed it with trhee ecus: p28, p73, & p72 still no response
THE ecu only reads the O2 sensor
ALL THIS WORK AND NO v tec???????????

for some reason my v tec won't engage and my car is topping out at about 7,500 to 8,000 rpm but it barely makes it there it struggles to get there
i get no responce from my v tec at all
the engine is a 1995 gsr the car is a 1996 gsr
all the wire harness are good they are all v tec
at first i noticed that the machine shop took out the valve inside the
v tec solenoid but i quickly replaced it and put back with the spring and everything
i tryed running the wires straight to the computer and received no response

is there something wrong with my engine because of the low redline or is that just because of the v tec not engaging?????????????????????????????????????
