Bullet proof heads?

Bullet proof heads?
What would be the best parts to put into a set of 241 castings that are home ported and polished? I'm running a TR224 with comp918's. I know the springs are rated to .600 lift but is this the best way to go? Would duals w/tit ret's be better? what about lifters? comp-r's are popular. What about Rockers as well?
I dont want to build a million dollar pair of ls1 241 heads, just keeping myself busy til I can afford some ls6's. But if I can swap the componants over, except maybe the seats and seals or can you swap them to? I'll put the good stuff into them now.

The 918s are fine, doubles are extra insurance. Stock rockers are practically bullet proof, except of course the needle bearings that some people have had spill. You could have Nasty Performance upgrade the rockers for you. Titanium retainers should be a must for you, light weight, strong, whats not to like! Upgraded valves if you want to go all the way, Manley, Ferrea, REV. Stock lifters are very strong also, but high mileage ones should be replaced I think. Comp OEM replacments or Morels, no need for Comp Rs unless your wanting an adjustable valvetrain. Also some upgraded Comp Pushrods. Good Luck

Best parts LS6 valves, 918's and titanium retainers. for that "smallish" cam they are more than plenty, and only ~127gr/valve moving assembly (ie: LIGHT).
That is what i run on mine on an XE-R 224/220.

LPE has their S.S 2.02 valves for $79 but I couldnt find the 1.57. Those would be my first choice for the price/perf

Stock valves are 2.00/1.55, 2.02/1.57 will need machining.
Get sodium filled hollow 02> LS6 valves on the intake and stock 1.55 exhaust. no seat machining required.
