L98 Heads Ultimate Performance Setup?
I have a set of L98 heads that I want to set up on my 91 Z28. I want to do the works to these heads. What is the best things to do to them? Do I need to look into 2.02 valves? I want the car to run low levels on the bottle and 12s on the motor. I know there are better heads out there but I have these already. Thanks, Brandon

"The Corvette L-98 head lends itself to excellent flow with some intelligent port work. Valve size is limited by the factory seat inserts to 2.00/1.56-inch valves but with the proper port work these heads can generate up to 250 cfm of intake flow at .500-inch valve lift with an excellent E/I above 70 percent." -John Lingenfelter, On Modifying Small-Block Chevy Engines.
