hey CIA, i have your 4-2-1 header and am having some headwork done. i need to see what size the openings are on the primaries so i can have them matched. do you guys have this info? also, how much would it be for a new gasket, i had to use a stock one and dremel it out lol.

Isn't it past your bedtime?

:p:

I'd try to answer your question but.. I'd be a liar if I did.

if you need a new header gasket(header to head) i have one im not using in the garage, if you want u can have it for 15shipped, oh and CIA lets u chose between 1.5" primaries and 1.75" so u'd have to find out which one u have, than take into consideration thats its OD not ID

pull it off and measure it...

i dont feel like taking off the header, this is the easier solution

but arent u taking the head off? the header will be out in the open than, just measure it and tell the shop

because the work is being done on a spare head. i dont need people arguing with me, if you dont know, dont contribute, i asked a simple question.

Give em a call, beth should be in (unless she is on vaca or something) and she should be able to look up your order and tell you which you had ordered, I know they are not on here as much as some cause they are swamped getting product out and doing r&d stuff
