Great street motors, and a few tweaks to the TPI setup will help them breath a bit more and give them a little bit more top end.

My buddy just did a decent amount of top end work on his 91 vette (thats the L98 but with the LT1 bumpers). cam... ported TPI and some other stuff and it dyno'd some impressive numbers.
