SVO heads

[Simon]

Are these good heads? Not after ultimate power.

Can't say just looking at pictures. You should know the CCs and disassemble them for a close inspection, rocker arm ratio as well as checking flatness. They could be just fine depending what you want to do with your car !!!

Lots of aluminum heads for Winsors SBF's . It depends on price, intended use, etc, My personal choice are AFR's. They are not the cheapest but you can't beat the quality. Especially their CNCed versions.

The heads seem to have adjustable ends on the roller rockers…is this normal? Can this type of rocker be used with hydraulic lifters?
Thanks

looks like a part number in the casting on the floor of the rocker area. Maybe google that and see what you come up with.

I had the J302 heads when they first came out, which was the first aluminum head offered by Ford (Alan Root designed). Loved the weight, but power didn't seem any different against a well-prepped iron factory head. I'm with Howard though in that later on, I installed some AFR 205s, and they transformed the motor, which validated what was being published about how superior it was to the J302. Perhaps Ford improved these heads over the years, to improve them from the original offering.
