New Gen3 Hemi Head for S/S

sugar1366 · 07-19-2012, 09:27 PM

NHRA has a new head listed for 5.7,6.1+6.4 in S/S only. It is casting #05037369BD and has larger port volumes. Does anyone know what head this is? Is it the 6.4 head?

It's the 6.4 head. Has larger valves, and a very nice runner, port etc. The valve guide is moved up into the spring leaving a very smooth port. That part might be available as a 'recon' only, which means it will be new w/valves, but you need a like number core. Mopar is trying to get some made for racing as bare. They were originally ok for stock till someone looked at them. Send me an email and I can give you more details if you want them. jefft@southlanddodge.com Supply has been a problem for all the Gen III heads in addition to others.

Jeff,

Are the stock 6.4 head port volume below 190cc intake?

If you want you can PM me.

You will have to putty them up to get the cc's right. They are a little larger.

Are they enough better that I should sell my stock 6.1 heads and get the new ones, or just get the 6.1's done? That is, if I ever get started on the engine.

Thanks Jeff,
