What header bolts for TTI?

Headers were brand new. No bolts in the box. Maybe I’ll give TTI a call tomorrow.
So did you call TTI? as have been said,should be included in the box,with gaskets,stickers,destructionsmanual and reducers/collectorextensions .

I sure wish ARP would increase the length of their header bolts from 3/4" to 1".... Dunno why they make them so short... if you have 3/8" flanges, and then use a gasket, you have less than 3/8 of thread engagement, which is not really enough IMO.

ARP is so hard to work with, if you're not a top fuel dragster they kinda piss on you. I inquired on them making some longer valve cover studs for the small block Mopar and they quoted me a THOUSAND dollars. All day I repeated that number in my head and just laughed like I was high on crack. What a jiffy.

They probably make them for the most popular application wish is headers with much thinner flanges.

Its not realy that strange,its pretty common with companys that produce things.
Its hard to make a profit on limited runs of a product,much better to work with catalog items/sets and thru dealers compared to dealing direct with customers who take a whole lot of time to help per sold item compared to selling say 1000 items to one single customer in one single order and the most common way to deal with this is to offer customers to order their specials if they want to but then it will cost bigtime and that keeps those small batches very limited,
For what its worth,you may find something already available in their catalog that fits your desired use but in a different secion (most certainly for something chevy) and it does not even need to be valvecoverstuds,could possibly even be oilpan studs that comes in a package and fits your application.
Laugh all you want but i doubt you are anywhere close to the succes of the people at ARP.
