I bought an LQ4 with approx 45K on it. You think it would be fine to reuse the main, and head bolts or should I replace them? I'm keeping it stock for now, just freshening it up. Thanks.

Replace them with ARP. The stock ones are only good once.

^x2. Only replace them with OEM ones if you don't have any plans on working on the engine

You are incorrect sir ... the heads can be removed with the engine in the car.

Stock head bolts are torque to yield, meaning they are tightened to the point where they are permenantly deformed. A set of ARP head bolts are not too awfully expensive and you are able to re-use them each time. So if you think you'll ever tear into it more than this first time, you'll probably save money in the end by getting a set of ARP head bolts now instead of buying multiple sets of OEM head bolts.

Main bolts are reuseable. Most say a couple times is fine. After that its not worth risking it. Main cap bolts are not TTY.

You MUST replace the head bolts like everyone said. My brother and me are installing the MS4 cam, and new heads, and are using ALL new gaskets and head/damper bolts. And yes you can remove the heads from an f-body while the engine is in the car.

Main bolts are reusable... Make sure when doing the last step on torque sequence that after you degree the bolts you check every one of them and make sure that they are at least 70 lb/ft but no more than 75 lb/ft... This lets you know for sure that the bolts havn't stretched.
