hey im currently working on my 2003 silverado ss, i just instaled my cam 581.lift intake and exaust, im working on changing the valve spings and push rods right now, running a manacharger with 9psi of boost, jba headers, and nelson tunned cpu, my question is what i should gap my plugs at, the old ones were at .035 and im not sure if it should be smaller, also what my fuel press should be at an idel, its around 45psi and i think it should be at 50psi, it has the inline fuel pump but not the one in the tank, any input would be great im hoping get her running later, thanks

.032-.035 on the plugs. 50-52 at idle and I believe 58 when you pull the vacuum line off the regulator.

i gaped them at .032, fuel press is almost at 50 at an idle, i just put it all together it runs good i have a slight tick from the valve cover not sure if its a rocker or not, i dont know its the new springs breaking in or not of a lose rocker, im gona flush out the all my coolent, coolent is green and the intercooler is orange fuild, im not sure if there mixing or not, im gona put some more time on it see if the noise progresses, break the cpu in some more
