You will end up doing more mods later...if your like all the rest of us. Get the large headers now. JMO

I agree. get the larger headers.

yes,..IF you are goiing to MOD it more then just bolt ons,..like, adding a blower or large cubic inches,..buy the bigger headers. but, if its only going to be a bolt on car,... there is no need.

Velocity and small cubes rule. But,..again,..only if its gonna be a bolt on setup.

if im going to add more parts it will be just a cam and a set of heads.

i need to compare the prices and decide

thank you

Just get the 1 7/8 regardless. Evey dyno run I have seen with 1 7/8 headers always put out more hp than the 1 3/4. There is millions of threads on this subject. And I have yet to see low end torque being killed b/c they used 1 7/8 primary headers.
