Stay away from pro comp heads for marine use.

if you do a little research on the differences between the 2 metals allu. vs iron/steel you will come to the conclusion that aluminum is a far superior material in just about all aspects
the biggest disadvantage to aluminum is that in a motor application if any overheating occurs even in small pockets this can adversely affect the metal itself
warping of heads is probably the most common problem
i wonder if some of the real serious hp enthusiasts are using billet aluminum blocks in marine application like the racing boys

Don't retract your statement! Procomp heads ARE made in China! They are routed through Austraila not MADE there! Do a quick google search on this and you'll find lots of info on them 90% of it bad! Do yourself a favor and stick with Dart, AFR, Merlin or Brodix.

when i got my AFR heads 3 weeks ago it was about a $150 option, per set, when i priced Brodix heads they were almost $500 or more a set, to hard anodize....
Thanks

That's what I thought but wasn't 100% sure, so now you confirmed what my wife tells me is false................ I DO know everything and I'm never wrong!
I've seen several alum. SBC heads that look identical but have different name and the same poor quality. Patriot, Pro Comp, Professional Products etc.... People buy them because they are cheap and don't care to investigate why whether it's poor design, poor flow characteristics, poor chamber design etc.... We only use American made parts on our engines and it's all we sell. Says so right on the top of our homepage![Smilie](/forums/images/smilies/smile.gif)

Merc. 496 heads are iron unless you have installed a set of our all USA made BigPower 100 lbs. less per pair aluminum heads!
