You are at the limit on the stock valve springs. You probably won't have coil bind or float valves at 4600-4800 rpm's but if you decide to replace the camshaft the springs will need to be changed.

I was looking at doing all of the above when I had my TriStar. Actually had the GT40P heads and the Edelbrock manifold. Then I sold the boat. Such is life.

If you are going to be into your engine anyway, the next thing to look at is the cam. The go-to people are Cam Research. They specialize in Ford cams and have experience in grinds for marine engines.

There are some good threads here (use search function) on the GT40 heads:

Stare at it long enough and bam! . . . it will just assemble itself before your eyes. LOL

Yea I don't see me doing anything with the cam just yet I'm over budget with the wife as it is but hey it had to look good and run good. I'd already have this all done but I'm waiting on the boat to get back from the fiberglass place and waiting on the heads to get finished up then it's game time.

I read on another thread today about clear coating valve covers and intake manifold to help with corrosion on the aluminum. Has anybody ever done this if so did you worry about over spray or did you tape everything off and also what kind of clear coat did you use?

I've had several auto engines with aluminum intakes and never had them corrode, even after 25 years. Not sure if marine engines would be any different.
