tapping at startup
 

I have a relatively new Coast High 347 with edlebrock alum heads that has a taaping sound like lifter noise or something in the valvetrain. The noise goes away in less than a minute so I'm wondering if the oil is getting to them. My oil pressure is ok.

Please help me out. Will an oil additive help?
