My friend that I bought the 2 from thinks the stock HG is shot, were going to take it apart anyways so I figure if you have it open you might as well upgrade to a MHG. I think I'll probably get the TRD one. . .sab0276 said:Headgasket depends on what thickness you want. I beleive most MHG are made by the same manufacturer but sold by different companies in different thicknesses.
Is there are reason you are upgrading the block? There really isn't a need to with just a CT27.
Most people use Fidanza lightweight flywheel and Spec Stage 3 clutch.
