FP Forced Performance Manifold, bolts washers needed?

[RedTurboEclipse]

I understand that the back 2 uses the standard oem long bolts with 2 washers per bolt..

how bout the front? People are saying to use oem o2 housing short bolts as thats what was included in earlier buys from FP. However I've seen pics and seen people are not using any washers on the front bolts?

Is this the preferred method or should i follow oem type setup and still add 2 washers.

I use the conical washers on all 4 bolts with the FP manifold.

if im not mistaken those manifolds use the evo front bolts. with two washers. because the evo bolts are shorter

Or o2 housing bolts work fine as well.

BTW i did end up using 2 washers (OEM conical) per bolt as per OEM install.

I used them in the front for my install last weekend. If you don't have conical washers, just make sure to use a good copper-based antisieze and hot torque them. Mine never came loose after I did that.
