Suspicious.

Not necessarily 180 degrees--even a couple of tooths out would do.

Other possibility is that ignition timing way off--distributor might be
180 degrees out. Easy to check. It seems very likely to be either
ignition timing or valve timing. Try ignition timing first, and if it
checks out, make sure both no. 1 valves are fully shut when the timing
mark indicates TDC and the distributor rotor points to the number 1 plug
contact.
