Install 2.02 Valves in 4343475 Heads?

the 308 heads were the swirl port heads for 360...started in 1989 with the LA 360 roller cam engines...

if you have bowl work done on the heads while installing the larger valve ...you will see pretty performance...if your heads have multiple valve jobs and the valves are sunk...installing a larger valve to get the valve back where it is suppose to be...you will see pretty performance...
