What size headers should I use? My motor is my 2303cc W/E120 /125 rockers. Jeff Deham welded heads, 42x37, and IDA's, will run it at Drag Day if all goes to plan. I want it for performance. What you guy's think? Thanks.  Roll Eyes

I would probably error towards the big side because of the motor size & go 1 3/4. the cam & rocker selection might be a bit on the small side. what vents. are going to use ?
