Sounds like 180* out to me. Pull the dist. bring up to tdc with your finger in hole it will push compression out. On exhaust stroke at tdc the exhaust valve is fully open. look inside the motor with a flash light and turn the oil pump so the dist. will drop where the rotor points towards #1 cylinder and the dist. has adjustment forwards and backwards.
Not saying it's perfect, just how I do it.
