Question

Valve size?

What's the valve size of the 98? 2.02.1.94? should I upgrade since I'm porting and polishing the heads? What are a good replacement type? I've got bent valves, that's the main reason for the head removal.

Default

The LS style engines use 2.00/1.55 except the 4.8/5.3 wich use a smaller intake valve due to a smaller bore. If you have to buy valves, upgrade to 2.02/1.57
