Hi everybody I just got my heads back after buying them from a member on this forum. The heads needed some work and got milled .010 For a total of .035 .040 The valves have been sunk down into the heads given only total .025 as if heads were only milled to get them ready and flat because they we're not ready to go as promised long story short I'm going with a cam 238/254 duration @ .050 .635/.624-112 lsa . Not disclosing anything yet but we are shooting for substantial amount of torque with horsepower to be equal since a lot of guys like both. My heads have 60k on them I will let everyone know the guide wear if any since my car has had tune and headers since 30k miles since I bought it at 28600 miles. Build date was 11/06 released as an 07. Motor was built by Tom M. After I get my heads checked they will be for sale soon by next 2 weeks anybody who is interested make me an offer I can get them freshened up or sale them as is. Thanks everyone I want to see how my heads are after 60k on this car no tracking at all just driving red lined 3 times in 4 years. I am using 13/4 headers with full cat back exhaust. I will be porting the manifold and tb. Stay tuned And get ready to go guys guess my Dyno numbers and ill buy anyone dinner for 2...
