I have a 01 TA M6 and I was wondering when I get my h/c setup would 2.05 on the intake be too much for my 346?

need more info. what are your plans and goals? while a 2.055 is a bit large for a 346 it is not necessarily to large.

I want to turn the car into a nice street/strip car with all the bolt on's. I would like to be in the mid 400 rwhp range running low 11's. The cam i was thinking of running is a F11 cam.

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 have 2.055 on mine. 1.58 exaust. I like'em. My launches are stronger now. My best 60' is 1.77

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....

i was told that the 2.05 will not hurt power but the gain in flow is minimal .....maybe
1-5 cfm differance..... its the porting that can hurt you, not the valves.

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.
