Yep! How'd you guess?
I'm doing a 1600 rebuild. It'll also have higher compression (9.5:1), a slightly different cam profile from stock (more like the 1975-1979 fuel injected Beetle cam profile, but with the larger carbureted valves.) and a CB Magnaspark digital distributor. I just got the rotating assembly balanced. I'm trying to do my rods and pistons myself.
I didn't get the external coating for the heads. I have brand new OEM dual port heads from Mexico. The cost was prohibitive to get the thermal shedding coat. I did paint my cylinders, but they are cast iron. I also painted the magnesium crankcase. I don't think painting the heads would be a good idea, unless it were the special thermal shedding coat, like the one offered by Swain Tech. Do you have any other ideas of how to reduce the aluminum oxide layer?
As far as engine cooling, I did all the HVX mods and put grooves in the rods (you can see them in the pic if you look close) like was mandated by VW for Type 4 engines. In stead of an external oil cooler (as recommended in the HVX mods) I went with a Type 4 oil cooler in place of the stock oil cooler, with a modified doghouse cooling shroud.
