I want to start off by saying thank you for everyone's patients. This project got put on hold for a couple of years because I purchased a new property for my business. The building needed allot more renovation than I had anticipated and hence the delay of the cylinder head program. I am back on track now, and I just received word from the foundry that I will have castings for my initial approval in about 2 weeks. After we do some close scrutinizing of the heads to make certain every thing is were it is supposed to be and the castings meet my approval. We will have these castings machined and do some flow testing along with mock ups on an engine block to verify the head is how I designed it. If I like the results I will be taking orders for the heads following these procedures. I will post the results as I get them here to keep everyone up to date as we progress. Below is a list of features that the DCI Ram Air V heads are designed with.


* Stock appearing on the outside correct in every detail right down to the A I R bosses
and number 44 in the center of the head
* Raised Intake runners 1.5" over stock with a direct line of sight to the valve
* High velocity intake ports with a cast in pushrod tube air foil
* Raised exhaust port exit (3/8") to straighten out the severe dog leg in the factory head
* Revised exhaust ports with a 1 7/8" round exit hole
* 3/4" deck surface for better head gasket retention
* Improved water jacket
* Capable of being used on factory blocks with a 4.180 bore size
* 10 degree valve inclination
* CNC machined 72cc and 85cc heart shaped combustion chambers for on the shelf
heads
* Heads will be cast without combustion chambers so custom combustion chambers
can be ordered to customers spec's
* Street versions will come with 2.200 intake valves and 1.68 exhaust valves
* Street versions can use stud mounted rockers with guide plates
* Race versions can be had with up to 2.450 intake valves for large bores
* Heads can be cast without water jackets for blown applications
* Heads will be available bare as well as complete ready to bolt on
* Bare castings will be as of right now $3150.00 bare and $4150.00 in street trim
