Default Headers Leak - New header bolts put in?

I installed my headers and have let my engine run for 10 minute sessions like 5 times. And I have leaks at where the header bolts are put in. Im retightenings the bolts but im really paranoid of breaking the stock bolt heads. So im thinking of picking up some stage 8 header bolts and retightening with those.

What do you guys think??

I put the puffy side of the gaskets face towards the headers while the intented side faced the block. Does anyone know if this is the correct way to have them on?

ps. and there Percy gaskets, not fel-pro I was wrong.

Stock GM gaskets work the best, new stock bolts, anti seeze and after the flange is tight next to the cyl head tighten from the inside out. thats the best.

Stage 8 Locking Header Bolts... $30 on sponsor sites, I paid $50 at a local shop, for Ford 4.6 header bolts, said they were the same size and was right. Working great!
