A friend of mine is building up an Iron Duke 4 cylinder and is looking for a cross flow head for this build. Does anyone have any info on this head, if it was ever made and where we might find one?
I'm thinking that the Pontiac 4 cyl. might have had one but not really sure.
Thanks for any info.

Can you modify a stock V8 head? Are the piston centers are the same? (seems like they should be if they are the same as the 230/250/292) You might be able to drill / tap new holes in deck surface for the head.

Years ago, Ansen made a aluminum 8 port head for the 62-70 Nova 153 cubic inch 4 cylinder motor.I can't remember if they were a crossflow head or not.Why don't you just go with one of the 2.5 GM engines that have a factory crossflow head already?---They have front and rear wheel drive types and are cheap to buy.Some have factory tubing headers.

The drag race guys drill and tap the deck of the block for a small block head. This way you have so many choices.
There was a guy that came to this site that built them motors. Kansas Racing produts I think. There are a ton of poeple doing this setup

Brodix made a head for this engine

isn't the iron duke the 2.5? i looked at a 2.5 out of an '85 s-10 and it's a cropssflow head, it even has factory tubing headers.

Try a vega GT head. I saw one the other day. Il go see if it is still there.
