Speedmaster aluminum heads

The SM heads are cheap as a OOTB cylinder head. If you have someone do any work to them, the cost savings disappears rapidly as with any other head. With that in mind, which seems to be forgotten here often with all the people saying “Save money, go with a SM head”, IMO, you better off going with what I always say, (“Afford yourself and-) Get the best head possible.

So many people have come back, argued and balked at that idea I write often about and suggest it’s silly. I guess, if YOU are going to DO THE UPGRADED WORK YOURSELF, it’s a deal. I don’t have a machine to kill the head down, do a valve job & as many others, I lack porting skills that really make the head into something nice.

A few years back, I purchased a set of CNC’d heads from ProMaxx which are the chink castings reworked here in the USA in Alabama. This is before the Trick Flow heads came out. IMO, probably the best “Replacement style” cylinder head at the time.
I also, before the TF heads came out, went with a set of W5 heads.

If I didn’t have cylinder heads today, I’d run Victors for a max power output engine, Trick Flows for a powerful street engine.
I wouldn’t waste time with anything else.

In the long run, it’s better to spend on the better cylinder head up front rather than a lesser head only to spend more on it later to upgrade it and probably, most probably, fall short of the better head for what would most likely be less money over all.

As someone has in their sig… pick your parts, pay your money.

Then live with the limitations and the cost of upgrading.
