how many of you guys have or recommend getting the head/block machined before putting a 2mm headgasket on? and are ARP studs a must or what?
SSS... close but no cigar. Sure the lower C/R reduces the chance of detonation, but *proper* piston squish helps, too. Unfortunately, raising the squish above 0.060" (Toyco spec) all but elminates the effect of proper squish. Adding a thicker hg basically blows away the squish effect.SSSUPRA said:No, A thicker HG lowers the CR which decreases the chances of detonation when boosted.
