Hi Guys
We tested the heads here in australia on our alcohol dragster for the guys at NRE for 12 months before they went on sale, Jamie the owner of NRE crews on our car, they are a direct replacement for the BAE -6 or -8, they take the same intake valve as an -8 but takes its own exhaust valve that is larger and longer to accomodate the same intake and exhaust installed heights. In the early stages we had to change back to our -6's between rounds and did so with no problems only thing we had to change was our exhaust pushrods. I would use the external oil feeds in the heads with a restrictor but they can be blocked and std block oiling used, all your valve covers, headers, rockers, manifolds from-8's, -6's and -5's will fit straight on, if you are going from -5's you will need the end spacers like Will said but you will also have to relieve your rocker covers for exhaust spring clearance just like the -6's, and all your pushrods will have to change, as far as i know they are the lightest and highest flowing head on the market, they also incorporate an oil gallery that has spring oiler jets for the intake springs, you can order them with iron or berilium valve seats and they have a promod legal head also with the 2.400 and 1.900 valve sizes. As Will said you will have to richen up your fuel system as it will require more fuel.
You can purchase them here in Australia through NRE or through Jeff Burnett, he is the USA distributor.

 

NRE Alcohol Heads

We will have a set of NRE heads on display at the IMIS trade show in the Indianapolis convention center this December 2nd and 3rd.

They are very nice and the flow charts will back that statement up. The configuration of the head allows you to use your existing intake manifold, valve covers, rocker assembly, etc. The valve cover rail has been raised to eliminate oil spillage during service but the spark plug tubes remain the same length.
The head also has been designed to allow the use of a pushrod as large as .625 in diameter!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

We highly suggest you consider this option. The head is outstanding.

The show is a hard core show only and is one week before the Florida show.
