I did that and they still sound kinda loud when it heats up. I just drove the car like 6 blocks on the slow hill in front of my house. The motor also has lash caps on it to correct the roller rocker/valve tip geometry. Could that be making the extra noise? I'm thinking I should adjust the valves tighter but how tight? if your dreaming of your car then it's your dream car....

It was in park and the water temp was prolly around 210 the rockers were hot when I set it to .18 but I haven't driven it around then adjusted right after. This was my first little drive in it. I don't have the cam card with me, I will have it tomorrow. But it's .522 107 lobe center installed straight up. solid crower lifters if your dreaming of your car then it's your dream car....

I set mine at .012/.012 cold. I seem to be having some noise up top I'm not confortable with. I re-check lash yesterday and it was fine. I think maybe the rockers and hitting the valve covers?? They are H/S and are reallt FAT. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

I had this issue recently with a small block with stock rocker arms. 70 Charger R/T SE 472 Hemi 70 Charger R/T convertible 70 Charger R/T V Code Sixpack 69 Charger R/T SE Sunroofcar 68 Charger 383 68 Charger 318 71 Charger R/T 70 Challenger convertible 71 Challenger convertible 71 Cuda 340 09 Challenger R/T Classic
