new guy here

Welcome to the board, 302mustang68. It sounds like you have a nice one. I'm sure one of the guys here will help you with the pushrod pushrod length. I've got to say that I have had pretty good luck with TFS pushrods, and FMS B351 1.6:1, and Crane's Gold series 1.6:1 ratio RRs in the past. Given the somewhat low lift numbers for the E303 cam, you might consider 1.7:1 RRs. Be sure to check PTV clearance, though you shouldn't have an issue, and make sure you have a good set of springs.

The answer to the pushrod length is you have to measure. Don't take anyone's word for it. Buy a checker and measure for yourself.

I like the COMP Gold rockers and, as FastDriver says, 1.7's would not be a bad idea.

Comp or TFS pushrods are a good choice as well.

I would also recommend making sure your springs are up to the task of the new cam. If you have stock heads that gets a bit tricky as the spring choices are limited due to the low IH. Be advised that springs wear out and the stock springs are only good for a stock cam. You have to make sure you don't coil bind and just as important you need to make sure the spring pressures are right.

Last E cam I installed it cost over $250 in springs and hardware. Now this was a different application than yours so you probabaly won't need as much spring but you still need to make sure you use what is recommended.
