Best Companies for Internal Parts?

I have been a long time ClubRSX member and recently just found out about thtis site. I am going to go NA on my car and want to extract ever bit of HP from my motor. I see so many different companies for parts and was just wondering from people with experience what have they found to gain them the most HP or be the best parts for longevity? I was thinking of going all TODA parts but I know other companies do the same parts for less and maybe even better. So just wanted to know what companies you guys reccomend for each internal part or for overall? Valves, springs, retainers, head gasket, pistons, connecting rods, crank, camshafts, etc.? Thanks for your help.

If this has already been covered sorry I couldn't find it but if someone would post a link to that post I will just read that. Thanx again.
