Totally new at this

Like title states, new to engine building. By trade I work for a company that makes precision instruments for pipeline construction where our tolerances are typically .015” so precision and caution is something I’m familiar with. If it should go in smooth it does, feel resistance and you know you fudged up somewhere.

With that being said I am a proud owner of a 2005 LS2 Corvette with some modifications done to it. She is cammed with a torque converter and headers. Now, the shop that did all of the performance work doesn’t have the data on whether or not the cam kit also upgraded lifters and the lower end to accommodate all the new inputs.

With all this said, the corvette is a weekend car and not a daily, realistically for someone who has a mechanical aptitude how difficult would a rip out and re-build be on this LS2? I’d love to bullet proof the lower end and valve train if possible but am weary about doing it myself without some sort of guidance having never rebuilt an engine before
