I was looking at arp and was gunna get those, but I was gunna take a look at my options

 

I am running the Percy's split header bolts and not had to tighten ever.... They have been on over four years!!!!!

 

I re-used my stock manifold bolts on my 08 .. I didnt put headers on until last year so almost 4yrs worth of Sth Louisiana rain n humidity and the stock bolts came right out with no issues ... I put a dab of never seize for alloy i had at work in case i need to remove them then tightened em up on the headers with no issues to date .. Over a yrs worth of same crappy sth louisiana humidty and rain and no loose bolts yet .. Daily driven over 40,000 a year .. Currently on blocks with 155,00 miles waitin on 6l80e trans Friday ... I will chk the bolts again before cranking up to see if any backed out ... If they did i will post ...

 

I used these on my LPP headers last week
