If I go with cc503 (ported stock heads, 355 fresh build, 10.5-11:1, ported intake) what is best valve train within reason (no endurance racing stuff that costs crazy amounts) should I go with? I'm still learning so top end stuff is cloudy to me.

Any part numbers with suggestions are highly appreciated. I know I've asked similar threads before but things wanted have worked there way down to realistic for daily driver parts. So close to this rebuild. So tired of stock 93, even if it is a tiny bit of a factory freak (CAI + ORY 6speed ran 13.4 on 245 all seasons)

Edit: Many people seem to be running 1.65RRs with that cam because of the low lift. Who makes good ones and where can I find some? Also, read good things about Beehive springs but the only ones I can find listed on Summit say for Gen I SBCs but doesn't list LT1s.

Needed Parts:
Retainers
Locks
Valve Stem Seals
Timing Chain and Gears
Pushrods
Rocker Arms

What suggestions can you guys make?

Here is what I would recommend:

Comp Pro Magnum 1.6 non self-aligning rockers for 7/16" studs.
ARP 7/16" rocker studs.
Trick Flow chrome-moly pushrods, 7.2" length (if everything else is stock, otherwise measure.).
OEM LS7 lifters.
PAC 1220 beehives with hardware.

i ran a 224/224 .550/.550 custom comp cam with the Crane 10308 valvesprings (come with springs, shims, retainers and locks) but i think the kit is no longer made and hard to get so you'll have to find some valvesprings and all that to work. i ran GMPP 3/8 SA 1.6 rockers and loved them, also ran some hardened stock length Comp pushrods and my original 100k mile lt1 lifters. bought a new factory timing chain from Carquest and some OEM replacement valve seals from Autozone. good luck man

^^X2 on the OE type timing parts:

(Didn't see your car's year...)

For 93-94 cars use OE replacements, they're plenty stout:

10128485 Chain
10128346 Crank Sprocket
10128349 Cam Sprocket

For 95-97 cars more kits are available are not worth the extra cost, i.e. "Extreme Duty"

I just finished putting a motor together with that cam. I used Comp 1.6 ultra pro mags. Just the pro mags would also be goodl. I havn't seen many 1.65 rockers if any, but with 1.60 rockers the valve lift is .537/.544@ .050. I got mine on ebay. Just do a search for "comp lt1 rockers" then you can pick from the different ratios and decide if you want the Ultra pros or the pro mags. I just replaced the lifters and pushrods with stockers and i am running these springs
