Why shovel out big bucks for that brand gasket when a Fel-Pro 1016 works perfect.
With a Pontiac you can’t have a gasket with a dead on bore size to match the cylinder anyway due to the width of the chamber with the 67 and up heads, but even if you could having 4.150” bore gasket only gets you back like 1.7 CCs and that little amount will not make you any extra power.
However having a notch / intake valve chamfer in the
top of the bore and loosing 1.5 CCs is worth more power then the drop in compression.
