C.F.R.? Advise Please
on my 83 cj7 i have the 258ci inline six (stock with plastic valve cover) and i cant get the valve cover to seal, i know i can buy a steel or aluminum one for it, and i know i may or will have to drill and tap holes... bummer, but i found a really cheap one on amazon (here is the link Amazon.com: 1964-88 AMC/Jeep 199-232-258 Straight/Inline 6 Cylinder Steel Valve Cover - Chrome: Automotive ) but i have never heard of "c.f.r. preformance". so all i really would like to know is; is this company any good? also is there any better idea for me?
