Can anyone tell me 1. what casting these are [img]https://www.ebay.com/itm/291722416620?ViewItem=&item=291722416620[/img] -

ie Procomp, ProMaxx, 440 source, etc. I know anyone can put there name on a casting, I am just trying to figure out what would be comparable.

2. If they are worth buying for a daily driver or are they scrap metal?

Thank you sir, looks like these are the same casting as the sidewinder or promaxx head based on that thread since they do not have the heart shaped chamber like the procomp/speedmaster crap.

It not sure how much faith to put in this but they call the intake valve 2.100”.

Typical valve size would be 2.14.


I used to care but....... things have changed

First of all it's not a 440Source head. They look different and I believe the casting was developed and is locked up by 440Source. If it wasn't there would have been other brands of the same head coming to market.

If you want to see what's available go to Alibaba.com and do a search for bigblock Mopar heads.

Looks like this head has 3/8" valve guides. That may narrow it down some. The ebay ad is full of mistakes.

Speaking of valve guides the guides and seats are the places that money is saved by the sellers of low-priced bare heads.

If you are searching for the lowest price head, I predict you'll get what you pay for.

Its a Speed Master head. Ive used a few using Ferrea valves and Comp springs, locks and retainers. Actually a cleaner casting than the 440 source head. Required much less machine work.
