Sometime soon I plan on geting new preformance rods and pistons on my 1995 RS. Since Im geting these new items would it be ok to raise my red line? I was thinking around 8,000 sounded good. Are there other parts that one should get if you want to do all this. I heard someguy said that an RS head cant handle valves going 8,000 rpms up and down in it.
