Valve springs for sure. The gt40 ones are a notorious week point on those heads. Also, cams and lifters wear together. Pick up a new set of lifters also.

I would start with the timing at 10* right after the install until you know everything is running good. Then you can advance it a little at a time up to 14* but going that high may require premium fuel, but well worth it imo. Just listen for pinging/detonation while driving under load.

It's all what you can afford. I think that 19 lb injectors will suffice for now. You can upgrade later to 24, but will need to tune or change maf also to match.
The lifters and timing set are a really good idea when changing the cam but not totally necessary. Again its what you can budget. I just picked up a set of trickflow lifters for 120$. I use a timing gear drive instead of a chain but they are more expensive.

+1, but I used ford racing lifters for 109. I believe trickflow uses the FR brand if I'm not mistaken so either ones are a great budget choice. A new chain is cheap insurance.

You need hydraulic roller lifters, any brand you choose is up to you. I was able to use my stock pushrods, but you may want to measure what you need just to be certain.

So as long as the push rods and lifters are correct measurements everything else will fall right into place?

If you plan in staying NA I would say the B-cam. If you plan on forced induction later on I would go with the E cam, it's a decent NA and FI cam. The trick flow stage 1 cam has a nice profile and lope to it as well.

I have the E and like its mild lope when it's warmed up but sometimes I wish it was a little choppier. The b cam and TF cam both have a decent choppy lope.

I run N/A and I run the f cam with trick flow heads. Idle has a nice lump and the car has great power and pull up to about 6500 rpms.
