We have the first set coming so stick around for our evaluation. The casting process is a good one and they're affordably priced. Stay Tuned!

Are these the same heads?

I'll be curious as to how much they weigh.

Still wouldn’t trust them. If you get a bad head from Edelbrock or KRE you got someone to complain to. A lot harder to get China on the phone even if they are being prepped by you guys

Has anyone established if China or Somewhere else?Tom

Got a reply that cost would be $1750 a pair set up for street, 72 cc. Not much more info.

These heads I'm evaluating are the SpeedMaster Heads like the Thread is Titled. I believe these heads are Made In China and they are not the Arrow Injuneering Heads we are developing.

These SpeedMaster Heads MAY be an affordable alternative to our ArrowHeads if they pass the quality test.

Answers are on the way!

Competition is a good thing, it brings down the prices some what. I can see Kaufman charging what he charges for his heads, he is a small manufacturer and has a quality tested part. On the other hand Edelbrock is a very large company and IMOP there cost on their Pontiac heads should be lower. Look at the prices of their Chevy heads ,then look at the Pontiac's. I'm sure they cost about the same to manufacturer . Just my to cent.

Isn't "Speedmaster" the re-named, re-branded, same-old-crap Pro Comp that had such a bad reputation?

You do know that if you have a problem with them, Speedmaster is in California yeah?

I bought one of their cranks on ebay.Was said to be a pontiac pin but when I got it,turned out to be BBC pin.They paid shipping back and credit in a day.No issue with dealing with them.Tom

My worry wouldn't be re: the warranty but rather the potential for failure:

How do we know quality of workmanship, valve seat install, quality of valvetrain, guides, springs, etc. If a substandard part breaks and destroys your engine, the best you can expect from them is likely replacement of the originally purchased part.

I doubt you would get more than that from ANY cylinder head supplier, Pontiac or other.

Danny Reegan didn't get ANYTHING from Edelbrock, when he had a head failure.

That's not inherently different than any other part you add to an engine. If memory serves me correct, I believe early run KRE heads had porosity issues with the casting. If a head leaked coolant into the engine and was run in that condition, you could be looking at bearing failure.

I don't know if that actually happened, but KRE wouldn't have replaced the heads and the bearings and pay for the rebuild. In fact, when I purchased my KRE D-ports, there was no warranty, implied or written. I'd like to think that KRE would step up to help is something had happened early on, but they wouldn't have been obligated to and I accepted that with my purchase.

That's part of hotrodding in general and something that almost any rodder will inevitably have to deal with at some point.

Where possible, I like to purchase goods made in the USA. I'm not however in denial that made in china automatically equals crap and made in USA automatically equals high quality.

I for one am down with anything that helps keep a Pontiac in a Pontiac. Even more so if the product is of good quality and at a competitive price. For that we should just thank Injun Engineering for testing out a set of these. If nothing else it'll provide some insight into the head and people can make the decision on if they want to purchase it.

I don't disagree - My point is the warranty isn't worth much if the part is likely to fail and destroys the engine - which is why you should invest in a quality part. Different scenario if the part is external and won't lunch your engine if it fails...

The only issue I take is that, nobody really yet knows what type of quality is being poured into these heads. Before completely writing them off, allow Injun Engineering to gather some data on them.

I have some guesses on what will be found. I'm not typically one to speculate, but based on what I've seen with automotive parts that you see in the cheaper category, it'll probably be a story of both good and bad.

My speculative idea is that the casting itself will probably be fine. The savings is probably coming by way of springs, valves etc. If that's the case and you have the ability to build the head yourself, or are planning to have a professional do it regardless, you may be money ahead by going with the Speedmaster over the Edelbrock or other offering.

I'm looking forward to their results. I read somewhere, CRS these days, that the e-head castings are nicer than the KREs, which some have mentioned have may have porosity issues. I don't know if any truth to that but if so, makes me wonder of likeliness Speedmaster's castings will be of quality. Also, e-heads have helicoils in bolt holes where I've read KRE's don't. If Speedmaster's have them it would be a good sign...I suppose...
