[QUOTE="7Lemons, post: 16601047, member: 184681"] I haven't posted in a while but have been chipping away at this build slowly but steadily. After this last post I ran into a ton of confusion over setting the cam timing and gen 1 vs gen 2 parts and installation instructions (gen 1 / gen 2 Ford manual procedures). So, I'll give the abridged version! In full disclosure here, I purchased the lightly used gen 2 heads, and all timing components (as stated before) from a guy in CA who was running it on his '14 GT, and was setup and tuned by Shaun@AED. This was a source of much confusion as the guy was not completely certain which parts were gen 1 vs gen 2 and when to follow gen 1 timing procedures vs gen 2 (not all that unexpectedly), as his car was setup by Shaun. After a couple key conversations first hand with Shaun, I was able to figure out what I have and what needed to be done (thanks Shaun). My daughter helping me install the roller followers and hydraulic lash adjuster assemblies: [ATTACH=full]1696821[/ATTACH] [ATTACH=full]1696820[/ATTACH] Here is where the mass confusion started. I order a billet crank sprocket from MMR along with the OPGs. I installed the sprocket and went to install my primary chain on the LH side... and NOPE! The teeth on the sprocket were not the same pitch as the chain!!?? [ATTACH=full]1696822[/ATTACH] [ATTACH=full]1696823[/ATTACH] Turns out my chain is a gen 2 chain and requires a gen 2 sprocket... but I thought I had to run all gen 1 timing components??!! Nope. Certain things MUST be gen 1 (on a gen 1 car) - such as the intake cams and the phasers for those intake cams. The gen 2 exhaust cams are essentially Boss exhaust cams, and they can be run in a gen 1 car but the phaser MUST match and is therefore a gen 2 phaser.
