NA GSR Build

[legacyo13]

I'm swapping a GSR motor into my civic, but i'm going to do some work before dropping it in. My question is, I'm looking at the valves, and I was wondering what the difference is between the exhaust and intake valves? If I bought 16 exhaust valves (thats how its sold), would I need to buy the 16 intake valves? The motors not in my posession yet, so I haven't got my hands on this, was shopping around and noticed this and was confused on a difference. Thanks in advanced.

um...there's 16 valves total..8 exhaust, 8 intake.
the intake valves are goin to be alittle bit bigger as well..if ur replacing one side..yes replace the other..it does effect the flow if some valves have a build up on them and some dont.

I wouldn't bother with flat faced valves unless some were bent or I was doing a full build on the head. A thinner head gasket get's you about the same compression increase. bBut a set of 16 is compete 8 intake 8 for exhaust.

I figured it was 8x8. I was wondering cause the site sells 16 exhaust valves, and a separate sale of 16 intake valves. So I was wondering. Each set is $344. I didn't know there was a size difference, I knew there was a temperature difference. It's a JDM B18C, so the compression is fine, I'm just trying to get more of a bang out of it and this confused me cause I've never worked on a head before, only motors and trannies. I forgot to mention the valves are racing spec ones from buddy club.
