ProComp/Speedmaster aluminum heads
There is this thread that that index does not include.. well though it's probably 68 painstaking pages 1/2 The Forum poking at each other there's probably some useful information in there as well...
But it starts off with me asking questions about these as the option wasn't available or I didn't know of it when I spent all that money on my cast-iron heads...
The question is do I wait for the sale or get them now with the free air gap style intake? You can never have to many intakes, but it's catch 22. Full price and intake or 30-40% off and no intake. Things to ponder.
