The saga of the '83 2.3T (Grab a beer and a snack) Reply #31 – September 08, 2007, 07:29:19 PM Ok, well I finally got the porting work done on the replacement head today. Nothing fancy, just some mild port work. One thing I did do was raise the roof of the big radius on the ex port to try and help smooth the flow. I basically just raised it by 1/8". Hard to really see in a pic and I forgot to take a side-by-side one.Next item is the little work for the oil-control cam bearings (which deliver the oil to the top of the cam bearing where the load is instead of the bottom. Then it's off to be faced and then time for reassembly. I went ahead and picked up a set of drop-in springs with a higher seat pressure as well. Quote Selected

I just want it back on the road. I just had a serious mental block with dropping a BONE STOCK head on it. Quote Selected
