Top overhaul (pt. II)

continue from part I...

the cylinder head was cleaned thoroughly with chemical to remove away all oil and carbon residue... because this cylinder head was from the old carburetored engine, the intake studs were shorter than those on fuel injection cylinder heads... i removed all of the intake studs and had them replaced with slightly longer stainless steel ones... this allows me to use teflon intake manifold gasket...

the next all important step is valve grinding... bought some grinding paste and took the whole afternoon grinding down each valve to make sure they sit well and no compression loss allowed...

and then finished by using AUTOSOL to ensure perfect seal...

valve spring were also uprated to stiffer ones from JASMA... they were claimed to have the same spec with RPW valve spring... see if you can differentiate between them both...

retainers were also replaced with light weight titanium retainers from JASMA... they are definitely lighter in weight compare to oem ones... unfortunately i forgot to scale them before installing...

viton valve seal were called in to prevent oil seeping into the combustion chamber...

to be continued...
