Valve Train Noise
I have an F13 cam in my car with some headers, I just recently put an electric cut out. The valve train sounds pretty noisy, almost sewing machine like. Is that normal? I checked the springs and the rockers and they are fine, i have chrom moly push rods, and the car has 62K on the clock. Am i just not used to hearing the valvetrain with the cam? The noise gets lounder and faster as it revs up. Let me know please

It will sound like a sewing machine with the F13 cam, perfectly normal... did you change oil recently? Sometimes a different oil weight, different brand, etc. can effect what you hear in the valvetrain if you're sensitive to the effects of those kinds of changes.

Well, Mobil 1's 5w30/10w30 are both fairly thin oils... it wouldn't help your valvetrain noise, it might actually make it a tad louder considering the 0w40 Mobil 1 is slightly thicker.
I had a little more valvetrain chatter with Mobil 1 as well (used the 0w40 as well as 5w30 before that), but it has gotten slightly quieter with the Amsoil XL 5w30 I'm running now. It's still audible though, as with a cam like F13 some sewing machine sound is to be expected.
