<VV> Banging Noise from Engine

[Matt]

Several members of my local CORSA chapter [ACORN] and I have been trying to
track down the source of the noise on a new member's car, a '65 Monza,
110-PG ['64 engine].  

2 years ago I was GIVEN a ”Banger” engine others had given up on.  Same scenario!

Turned out the one head had been over heated, dropped an intake seat and damaged the piston.

Piston replaced, but installed backwards[ notch to REAR, not towards bellhousing.

Seat replaced in head…  BUT  gasket register had   sunk or been cut.  Was 0.670” deep vs. 0.560” from factory.

Replaced head with good used unit and engine is fine today.

Try a different head!  Simple and fast to do.   Good Luck
