I know this is in the wrong section but I thought someone might have heard of these heads or the company that does the work? BRZEZINSKI RACING PRO D. NO 42886 S-1. It is a set of heads that I bought.

Thats all I could come up from a quick google search. Didnt take the time to look up the number on the actual site but I did on google with no results. With a little more info on your heads you should be able to match them to the product on the site.

 

I found the site. I was hoping that someone here might have an experience with the company.

 

they are a fairly good company. if the intake side was ported I hope you got the intake that goes with it as they are known for extensive porting for excellent high rpm flow numbers. if you are doing a high rev motor they are great like that but if doing a torque motor they will fall short of your expectations. hope this helps.

 

I bought the heads assembled with crane gold 1.6 roller rockers for $500. I did not get intake with it. If you know anyone looking for a setup like this they can have it for what it cost me.
