Stay faaaaar away from MMR.

I don't see how that sorry excuse for a business is still around.

 

Not gonna bash another company, but I can speak for Blow By Racing's heads - great product, solid cust service.

 

I'm taking it they are not the best company and that's fine, but what about the stage 2 heads? I bought a set off ebay that needs work, so now I'm wondering if I should fix them and run them on my car or fix and sale them, I guess I could take them to a diff porter and see what they think about them, if there is not any gains to be had using them, then I'll off them after I get them fixed...

 

I wouldn't buy anything from MMR but since you already have these I would take them to someone good with heads and have the heads check for cracks and straight decks. Then install new valves, the ones MMR uses have a bad habit of breaking and taking the motor with them. If you don't want to go to all this trouble and expense then sell the pieces of **** to some other unsuspecting guy and get some heads from Livernois. Livernois is currently the only company doing heads that use bronze valve guides standard. Most of the failures involving heads were caused by the valves binding in the stock guides at high power levels.
