Multi-air valve engine
Replaced engine block and re-engineered the cylinder head and put it back on with a timing tool that holds camshaft into place and crankshaft in place.
Vehicle cranks but not starting and has flames coming out of intake.
What could be the reason?

First place to check is the distributor ...it could be 180 degrees out of phase and adding spark at the wrong time ...when the intake valves are open. Been there done it. But on a 60's vintage car... also check to see if the cams are 180 out from TDC

No distributor on a multi-air. I think ignition is triggered off the flywheel, so I suppose that it might be possible to get the flywheel degreed onto the crank wrong when changing out a block, but probably it is just that the cam is 180 off. The holding tool has a flat piece that goes into where the vacuum pump normally goes. Pretty sure it will go in just as easily 180 off.

I just did a timing belt on a 1.4 multi-air. Of course, I didn't take the motor apart, so it was just a matter of rotating the engine to tdc and locking both halves down before removing the old belt.
