Title: Cylinder head upgrade
Post by: Jota69 on May 02, 2010, 05:13:08 PM

I am planning to rebuild my engine and in the process intall bigger valves, a 40/80 cam and I also want to skimm some off the head to raise the compression. What would be the maximum I can take off the head without having any problems?

Also as I mentioned I will be upgrading the valves, I was thinking 31mm exhaust and 36mm  intake. But I read somewhere that upgrading the exhaust valves would not yield any diference in performance, is this true?
