mk hammer marine
 

Has anyone used the hammer alum heads? If so to what results?
Does anyone know anything about the head castings?

i wonder who,s castings they use,for that kind of money i would not expect much.

thats my thoughts but i thought i'd check to see if anyone could clarify. and prove or disprove

I believe it was determined that the 502 blocks are imports, so one would assume that the heads are imports as well. If that's the case, I wouldn't expect all that much, just like the other imported heads.

They sell cast cams 2.

Be sure and let us know if you find any other info during your search. I'm curious how they flow as well. It would be nice to have the extra time and bucks to give some of theses deals a shot to see if their worthy. I noticed there's a place that sells a lot of aluminum heads online etc out in Fresno CA and AL. Wonder if their the same? I would imagine their from overseas "China" like pro comp etc. I'm not sure how the quality of aluminum is from over seas compared to that of in the US or is it all the same? In regards to bolt holes etc lining up even dart has had issues with that from time to time.

I tried pro comps 5 years back. They were assembled by white performance. Make good power but the castings were weak and would.strip.threads real easy.
I have a set of proheader heads that white performance built.for me and they are awesome. But with 330cc runners I want to go back to a smaller runner 310.or.so.for.better velocity and to help bottom end hole shot for a 509. . Will.probably go with a set of brodix from eddie. But I am just looking everything over. And exploring all options.

And thanks eddie for your input. Haven't been able to find out much

found out they r strike force castings basically on par with edlebroch

Nothing wrong with Edelbrock "castings", in fact they are high quality, made in the USA and are offered by Merc and GM hi perf; companies that actually have to honor warranties.
