Engine is a 59A in a 1940 Coupe. 276" with Fenton headers, Harman-Collins Cam and Magneto, Ford of Canada aluminum heads, Offy intake with 2-97's by Uncle Max.

I recently had the intake off and decided to block the two heat risers in the block with some steel 3/4 inch freeze plugs. Everything went well and the plugs tapped in firmly just just below the block surface.

The strange thing is that since doing this it seems that the exhaust noise at the tail pipes is much louder than it was before. I wouldn't think that this would be the case but has anyone experienced this before?
