Hey guys, I dropped a Race Engineering head into my 1.6 last season since I couldn't afford the whole sha-bang, and was having a conversation with someone about the combination of the lower end and race heads (I overheated a couple years ago to the point that the cylinder head at the time warped 0.017"- stupid coolant caps!) The bottom end that was over heated is the one currently in the car which hasn't been re-ringed, honed, sealed, bearings, etc. where the individual told me that overheated bottom ends in conjunction with a race head tend to make really decent power.
Is there any legitimacy to this claim? If so, why? I don't understand the science behind why an overheated motor might have an advantage over one that hasn't been previously?
I'm on the fence currently about sending the engine to my builder to check the head (and refresh if needed) as well as build the bottom end. Can't afford an NB at this time, but if anyone with a 1.6 that's went for a full motor; was it worth the cost? Or just stick with the head and junkyard bottom end?
