building my heads

is this a cam a little small? i saw one that was 292 509

and i saw on moparts a head with 2.02 valves with 1.60 ex is is this to big for the 302?

and isnt the 1.78 the orginal 302 valve size?

o and i jsut found out that the 302 pushrod size is 11/16 this is ok on my older 318 correct?
