Is your timing correct?

I set it at tdc and put the cams the right way and had 14 1/2 pins on the timing chain because i have hot cams i have no other clue what could be wrong

Are your valves shimmed to spec?

yea if your valves arent shimed correctly your exhaust might be opening late so when your intake is opening the exhaust is still some what open and your losing fuel through your pipe and losing fuel is also losing compression

is it popping or anything ?

what all did you rebuild ?

I have seen plugs that will fire when held to a ground but wont fire under compression

you need gas, compression and spark all in the right time
