whats going on guys im putting an ls1 in my mustang and found a killer deal on a 98 ls1 out of a vett. im going to convert it to a manual throttle body change the computer and harness and let it rip. however somebody told me they re designed the ls1 in 1999 to the center valve cover bolt design because they were having head gasket problems anybody hear about this? please toss your opinions up asap because im going sometime tomorrow to check out this motor.

thanks all

It has nothing to do with a head gasket problem. They don't have any head gasket problem anyway. The biggest differance is that it's alot easier to pull the valve covers with the center bolt covers. They claim the 97- early 2000 have weaker rod bolts but if ya don't wind it to the moon you won't have any problem. My 97 vette and 2000 ta have the so called weak rod bolts so I just keep it under 6500 rpms. But whoever said they have head problems was misinformed for sure

Nope head bolt pattern is the same. I would have to say that you will need an oil pan from the fbody since the vette pan is the wide flat pan. The pan in the fbody is more like the normal pan.
