Spark Plugs for 1968 327

AFR Eliminator with Magnum 270 cam

Quick look on the internets to see how much they are, and needless to say I'll be saving for a bit longer . So many head choices with the various CC versions - 185, 195, etc.... though looking at the names, anything more than 195 is labelled as "race". So probably not for me. Mine is more "my car was labelled as 300(gross)hp when new, and I want it to have at least 300(net)hp now, and be nicely streetable".

If in doubt, take one spark plug out and look at the head where the plug installs
If the surface is flat than not seated ,and if the surface shows tamper than for tapered type

I'm hoping to pull a plug sometime soon - just waiting for my new plug removal tool to arrive, and also some spare time when not looking after a baby etc.

Careful selection of your cylinder heads can make all the differerence in power and, more importantly 'streetability', and surprisingly perhaps economy (lets say 'relative' economy). You'll select the carb, the inlet manifold, headers and cam to hopefully suit the characteristics of the heads .........but that key selection is the cylinder head, its where the best money is spent.
