Help identifying pistons and cylinder heads

One of our members bought a set of cast iron heads from Speedmaster. He wasn’t real pleased with the flow numbers but for the price I’m betting they are way better than what you have. Maybe they will add more info if they see this.

Oh, if I go with aftermarket heads it will be aluminum. I think from what I looked at before, it would be like $700 for a set of the speedmaster aluminums setup for flat tappet (for the pair). I will only stay iron if I can find a cheaper set locally.

Did you measure the valve sizes yourself?
Are the intake port openings the 360 or 318 size?(in the pic, the exhaust port openings appear to be 318 sized to me)

Pretty much any new iron head you can buy now will be a magnum based head.

It’s not that big of a job to recut 1.78/1.50 seats for 1.88/1.60 valves.
(For me, I would only consider this if the heads have 360 sized intake ports. If they’re 318 sized ports, I’d look for some castings with 360 sized ports)
But depending on the overall condition of the heads, it’s possible to end up with a bigger bill reconditioning your old heads than many people think.
That will likely come down to what machine shop labor costs in your area are.

I think I mentioned it above, but I went out to the garage quick this morning to measure the valves, and they are indeed the 1.78/1.60.

The only iron heads I would purchase would be if I could find a reasonably priced factory casting with larger valves in them already. Otherwise I will look at aluminum aftermarket. Machine shop costs here are not cheap, so reworking factory heads is really not something in the budget unless I would be building a stock eliminator type deal where I had to use them.
