What are the valve lengths for this new head? I think it would be a good idea to use the sbscrubby stock length for availabilty and economy if possible? Has this be considered?

FIGHT CONFORMITY! 

Scrub valves are actually shorter than the Y valves.  In todays market, custom valves are very inexpensive when bought in quantity.  Likewise, there are a multitude of other valves already being used in other applications that may or may not fit the bill.  In the case of a new head design, it’s best to build or use a valve that’s best suited to the head and not the other way around.  I have complete confidence in John using the best valve for the application and not just making something fit.

Sometimes I think that I'm designing this head, sometimes it seems to have a mind of its own. Machined head has been cut up and no real problems encountered. I am driving up to Edelbrock tomorrow to check on a few things. Will make a few minor adjustments. They have enough cores to make 8 heads. After these 8 are cast we will retrieve core boxes to make permanent changes. At that point we will start taking deposits. First come, first served. The more valves, seats, guides, retainers, springs we buy, the better price we can get. This will help final cost.



At this point it has become necessary to make new rocker stands that will be included with the heads. This must be done to allow the use of existing valve covers. Just couldn't figure out any other way to relocate the valves, straighten the ports, and make existing valve covers fit along with 1.6:1 rockers. Having the valve covers held down by rocker studs really limits what can be changed. The new stands will have the bolt holes moved to 1.5" apart instead of 1.2" as stock. This will open the possibility for higher ratio rockers in the future. Pushrods will likely be the later 8.30" length.

Mar 19, that is a good day! My birthday and wedding anniversary! Looking forward to some dyno numbers on the heads comparied to the best cast heads. Thank you for all your hard work and best of luck with the finished product. Got my copy of the EMC Mag today and can only imagine what Ted's engine would have done with a set of these heads.
