Is 2.05 on the intake too much?
then yes 2.055 is too big
if your getting a killer deal on them though then i'd do it...but you will loose some low end power and torque. however if you ever go with a stroker or something later on they will work great. consider it getting ready for the big one

I made 426 RWHP/400 RWTQ using 2.05 intake's and 1.60's on the exhaust with my MTI stage II LS1 heads and a dinky B1 cam so I wouldn't rule out 2.05's too quickly! All depends on the porting work.

i'm considering using 2.05 intake valves this spring when i look into heads, probably on stg2 ls6's. these will be on my 346 for a while, then possibly be reworked for a larger bore. they will work for the standard 3.9 bore as long as the porter knows this going into the project, and everything is matched well enough. give TEA a call....

2.055 is what most of the top head offerings are using now. With a larger bore (4.XX they typically will go up to a 2.08 to 2.10 valve depending on bore size/application)
Certain S2 designated heads are using 2.02 but most of the all out heads seem to be coming with the 2.055
Personally I would not go smaller than 2.055 on the intake.
