I have a crazy project going and I am looking for an aluminum intake for a 302. I have two in mind but would like to know if either are significant in any way. The last time I asked a question I was set straight and right away and I thank all for that so here we go again.

the following casting numbers are what I am looking at....good...or no

RF E9TE 9K46 1A4A
RF E8ZE 94Z5 E4A

thanks for your input
