Guys, thanks for the input. Current heads are 101cc version which should give me CR around 7.8, right ? - doesn't sound good. What are recommendations regarding head - mill existing 6X-8's, swap 72 for 87cc aluminum (which should be right around CR of 9)?
Also forgot to mention I have purchased 1-5/8" ceramic coated Hooker Comp Headers and a 2.5" Pypes dual exhaust system as well...
