Haven't taken the engine apart yet, :wink: Those heads are spares. The polishing bits were delivered yesterday so I will get them finished this week hopefully, then I'll strip it down and play.
I am quite pleased with the MOT, just need to order a set of brake hoses on monday (may have to get braided) and I'll get it re-tested next week.
Actually no the brake issues aren't related. The unbalance application is down to dust buildup in the drums. I will clean out an re-adjust all 4 corners one evening and completley flush and bleed the brake fluid when I change the pipe. Hopefully he will stop a little better when I'm done but I doubt it.
