I was having the same problem until I quit using the RTV sealant. A guy gave me a tube of sealant and told me if I used it instead of the RTV I wouldn't have any more problems. He was right. I can't remember the name of it but I will look in the morning and post it.

Same thing with the water neck.

Ultra copper gasket sealer/maker, it is the best stuff made. Put a line front and rear, make sure to push it inthe the corners where the head meets the block. Set the intake down tighten the bolts, wait overnight and no leaky!! Be sure to clean the rails so it sticks the intake as well. It dries pliable but tough as nails and hold up to extreme heat. Its the only thing I use. It'll fix the four leaking bolts as well, but I think it might be a gasket issue, some intakes require a specific gasket to cover everything up and to not get any leaks.
