We get numerous emails and phone calls a week about having cylinder head work done. We get questions ranging from who can install valvetrain, to who we recommend for cylinder head porting. I have decided to put some cylinder head packages together that are both economical and offer great performance. We do not offer cylinder head porting, simply because I have made very good power from stock port cylinder heads. We do offer a 5 angle performance valve job that will allow for 80% of the flow potential from the cylinder head. This saves you money from not having the cylinder head ported, and fast turn around time at 2-3 weeks. We are offering quality valvetrain from both Skunk2 Racing and Manley Performance. The stage 1 package is meant for N/A, turbo, supercharger, or nitrous engines running OEM cams or up to Skunk2 Tuner 1 Cams. Maximum RPM is rated at 9,500, and is great for daily driver or street/strip applications. The stage 2 package is meant for N/A, turbo, supercharger, or nitrous engines running up to Skunk2 Pro 3 camshafts. Maximum RPM for this package is rated at 10,500 and is great for drag cars, street/strip cars or N/A cars running very high lift camshafts. You can see pricing and what is available for each stage HERE. If you have any questions concerning the cylinder head packages, please feel free to email tech@evans-tuning.com.
