Marine intake (not really needed for fresh water, more pricey):

Non marine, okay for fresh:

For the cam, go roller if you can as you should have a roller block. The flat tappet you list would be okay, but not as good as a roller setup.

^^ I'm now leaning toward the Vortec heads. ^^
Now thinking clearly without a migraine, I would still have to buy an intake, so the money paid out would be similar.
Would the 262H cam be ok with Vortec heads?

Pass.
I have hands on experience with that motor and it's the biggest dog known to mankind. Whoever in GMPP stuck that hunk of schit camshaft in that engine should get one up his azz.
A 260hp motor will run better. Way better !
That cam was designed for high compression engines back in the 60's. Lots of seat duration. It wasn't even that good for those motors back then.
Totally assinine.
A 300hp 5.7 motor can be almost built by mistake and run so much better then that hunk of crap 290hp/5.7.

Do you have a base motor to work with ? Or need to buy an engine ?
Are you looking for 300hp ? Or something else.
To be honest, I've been involved with some real brain draining diagnostics at work past few weeks, that I'm done with, so I'm in brainless cruise control right now............so I'm not quite sure what exactly you are up to.
