Pacesetter headers

[Joe Dirte]

Anyone use the pacesetters with the air tube and block it off? I tried half inch cap and 3/4 inch cap. Thinkin maybe it's 5/8? I may not even use them as I found a pair of ceramic coated ones with no air tube for decent price so gonna see if I can pick them up Tuesday but just in case the thread size would be appreciated.

If it's Vortec I used a 5/8" cap from Lowe's to block it off.
