Reply to "aluminum heads"

The easiest, least painful way to convert to alloy heads, that will require the least amount of additional new parts, is to purchase 4V heads from CHI. The CHI 4V head is basically their 3V head, with the intake port opening machined to the size of the oem 4V port.

AFD will also machine the ports of their 4V heads to the full size of the oem 4V port on special order. (AFD standard 4V head has a "stuffed" intake port configuration).

Another alternative would be to use the 2V head from either CHI or AFD and combine that with either an Edelbrock Performer 2V intake, or the new Edelbrock Perfromer RPM air-gap intake.

You can't go wrong with either choice, the 2V heads will make a better street motor. The 4V heads will allow use of certain 4V intake manifolds, like the Holley Strip Dominator, Blue Thunder, Boss 351, etc.

There are also high rise, single plane, spider intakes for 2V, 3V or 4V heads, although the price, to your door will be about $750 USD.
