65 Val,

Correct,

A 1968 - 273/190 HP with Flat-Top Pistons w/Notches.

Just a swap with 1967 273 {#920} Closed Chamber Heads, proving the Pistons
are 'below' deck.

Worth about a +10 HP gain.

...or, just swap '68/'69 273 /190HP pistons into a '67- down block w/early or "302" heads will accomplish the same thing?
