NDOMTUS,
I had my stock rod bolts replaced with Katech bolts when I had the TPIS headers installed. The oil pan needs to be removed to install the headers, which allows the bolts to be changed out. Also, if you go this route its wise to replace the pan gasket.
Bolts cost me $160.00, and that included overnight delivery. Katech bolts look beautiful-reeking of quality. Stock bolts look like something you would buy at a hardware store.....even the mechanic was impressed.
Why change out the bolts? Katech(They specialize in building racing engines-like the C5R 427 engine) has found, thru testing, that the weak link in the bottom of the LS1/LS6 engine is the rod bolts. It seems to me that if your serious about mo power, it's cheap insurance. Also, Chris at Katech said they have tested an LS1 for 24 hours at a steady 7200rpm with no bolt failures. Obviously, this was not a stock LS1.
HTH!!
