amazing heads

February 10, 2010
I put these heads on my new race motor we built mid season, first night with it in the car, the car ran better then ever. These heads breathe so well,come ready to just bolt on, and for the price, you could buy these or take a stock set to an engine shop and have em worked and maybe pay them more, so why not just get these,i know I will from now on.
Pros:
  • Price is great
  • All around great heads
  • Love the power add
  • Of the corner
  • Really feel it coming out
Yes, I recommend this product.

Do you have any headers that will fit these and clear the spark plug location? Preferably ones that can also fit into an s10 2wd 1984.

Yes we offer headers 41869520 which will fit these cylinder heads. These are straight plug heads so those header should clear the spark plugs. The issue I see is that the 1 1/2" primary tube is pretty small for the power potential of these cylinder heads. It will work fine but if you want a good street/strip combo an 1 5/8" primary tube would be a better choice. For normal street driving the 1 1/2" primary tube will be great.

Sorry we do not have flow specs on these discontinued RHS heads. You may want to search for some old info that RHS or an independent company published back when these cylinder heads were in production.
