What's with quality control these days. I used the spider and dogbones kit from Comp Cams. I found one of the dogbones was badly machined and the lifter support was cut 1/16" to wide and allowed the lifter to turn a fair bit. Not Good.



I got out the carbide burrs and tried my hand at portmatching the exhaust. The header tubes have a lot of weld overhang into the port so I cleaned them up.



AFR is offering a Competition porting and part of it is raising the port 1/8" and squaring out the corners. I trimmed the roof of the port up 1/8" and now it meets the top of the header. I didn't want to shorten the guide, so I did some dressing around that.



The intake gaskets, Felpro 1262, turned to mush around the water ports and any other place there was silicone. I'm trying the FRPP A50 steel laminated intake. It has Printoseal on both sides and I'm going to try it without extra silicone. Just Right Stuff is used across the ends.
