i want to "un-cork" the engine in my truck as i have recently learned while on this site that truck heads have small valves i came to a conclusion since it will be a dd i want to un-cork it with some "big-valve" heads and a four-barrel intake i know what intake i want but figured i would ask for your guys opinion so hears my questions, "what would a good set of heads be? how much would they cost? are johns aluminum ones out yet? what would a good intake option be? one that will accept modern carbs johns intake cought my eye i would like to get one of those if they are not really expensive.

"young bucks bring fresh ideas sometimes they work sometimes they dont but all the same it was an idea it wasnt the first it wont be the last either!"

For street use. G heads, B intake, late dist with some type ign upgrade, modern carb of your choice around 500 cfm. Search the forum, there is a ton of information on this combination.

Heads will cost anywhere from a couple hundred to 300-400 if they have been cleaned etc. I am talking NC prices. I paid $75.00 for a set of 113 heads had them worked and had about 300 in them with new valves ,springs seat etc. Post 57 distributor. Autozone/advance have 62 truck distributors for around 50.00 . You ned this because of the mechanical and vacuum advance. I have MSD ignition box and coil on mine . I have a Blue Thunder intake with a 415CFM Holley and 1" spacer and Ford Power train headers. When put together correctly, adjustments made properly, and all the buttons and whistles secure you should very easily blow off a cork or 2 with it.

As Glen mentions, the search function will bring up lots of information on both heads and intakes.  Just key in different search terms for a variety of information.

I’ll add that any of the big valve heads are a good starting point.  These include the G’s, 113’s, and 471’s.  The 471’s are considerably larger in combustion chamber size and are well suited to supercharger applications or for normally aspirated applications when using a domed piston.  Likewise, the 1956 ‘C’ heads also provide a decent step up in performance.

Here’s a recent post regarding the aluminum heads.   http://www.y-blocksforever.com/forums/Topic28100-11-3.aspx    In essence, the production is still several months off when taking pre-testing into consideration.

I have a pair of ECZ-C in east central IN.  Shipping cast iron can be expensive.

If I can horn in, shipping is likely quite some $$ If you can't find anything in Oregon, try this guy in Calif.. Mike Henaults, La Grange CA. 209-852-2476 or e mail heanaults@jps.net. He specializes in Y-Block engine & transmissions & even Oval track races them.

I shipped a pair of bare castings from here to Alabama a couple years ago.  Seems like it cost around $35-40 per head.  McTim in Ca has recently acquired a large stash of Y parts, he may be willing to sell you some heads.  He's a lot closer to you than I am.
