To be safe...
Just to be on the safe side..
Would anyone recommend me doing a head gasket on the stock VQ35 to lower the high compression on the stock setup. I'm not really ready to build the VQ35 engine so to be on the safe side I think this would be good option if I want to run FI without any worries.
By the way is the stock compression on the VQ35 11.1 or 10.5?

HKS Metal Head Gaskets
The HKS VQ35DE Metal Head Gaskets are 0.7mm thick and feature a 4-layer stopper-type structure. The stopper-type structure employs a stopper ring around each combustion chamber that is molded into the head gasket for a precise and strengthened seal. The factory head gasket is only made from 3 layers and has a bead-type structure. A bead-type head gasket only uses a raised bead to seal the combustion chamber. The HKS VQ35DE Metal Head Gaskets are targeted for forced induction and high-horsepower naturally aspirated applications.

Hmm, so far I'm finding examples of other guys using these, mainly S2000's and Audi TT's, but they don't say how thick the gaskets are.
Most are extreme though, like the S2K's lowers it a 1 full mark, while the TT's is lowered nearly 2, from 10.30:1 to 8.5:1.
I also see the stock compression ratio for the G as 10.3:1, but '07 may be 11.0:1, the sights I'm finding for the G aren't that credible.
