Relying on decking the head or block isn't an ideal form of increasing compression and is not the same as utilising high compression piston/rod combo. If you have the budget I'd suggest doing the rods + pistons now, it'll also help your off cam (and on cam for that matter) performance. The reason cars traditionally feel reallllly laggy off cam is that there overcammed.

Regarding decking, there are two factors at play that cause the reduced efficiency from increased compression from decking. One being flame propagation and the other being quench.

It's 4am so really dont have the presence of mind to post a well thought out post, sides you prolly already know this.

Still sweet build. <3 NA.
