Hughes rockers

Should work just fine once you get the correct pushrods in there and set the lash. Do you have a dial indicator that you can put on the retainer so you can measure actual lift at the valve? It is always good to double check the real rocker arm ratio since sometimes they aren't what they are supposed to be. I tested a bunch of Mopar rocker arms for Hot Rod.

I also have a solid valley cover and side shield combo that will work with those heads if the stock bathtub gasket doesn't work. Usually the bathtub gasket isn't large enough to work with fully ported heads. If you are interested just let me know. The parts are listed on my website in the valley plate section if you want to take a look.
