I will replace the cams, so new rocker arms, or reground rockers are needed - Roger.

If I replace the rockers, I considered new shafts would be also be requisite. Advice?

Another question - the cams sprocket (both) showed scratching - on the teeth facing the sprocket only. These were not deep, but did cause me to question if this wear type was normal - Slack until tensioner is fully engaged? Misaligned? I have new ramps and all the wear items in the cam assembly = gaskets, o-rings, pins, keys, and am considering adding new sprockets. I have new chains as well.

Fred, I want to do this right. I'm over 10G into this build... a few more thou was anticipated. My OCD - dirt, leaks, etc... has me venturing into other domains - the fan is fugly and that too will be cleaned and painted - spruced up. My buddy who helped me with the drop put a worm in my head when he suggested - WHy not do the pistons while yer at this? If that was not so costly, I probably would. The point being I want the motor clean, tight, and as pretty as I can make it while it is out. I have a pressure plate and clutch, new shocks, sway bars, and I'm considering a 993 brake package.

So Fred - if there is anything else you'd recommend, please tell me. Again, Thank you so much for all your help
I would consider upgrading to ARP rod bolts and head studs and anything else that improves durability/longevity. Maybe reconsider the 993 brake upgrade and save the dough for engine parts. I found the stock 930 brakes plenty powerful as long as you improve the cooling to them. I track my car all the time and never had a brake issue that race pads and fluid did not alleviate.
I went and upgraded the intercooler to a B&B and also got headers with the K27S turbo. These improved performance drastically.
Good luck.
