Rhs 360x

Hey are you gonna run .620? or .580 lift? how about .550 lift?

They flowed great with the valves that came with them, MAD DART is doing WAY MORE than you are, so don't confuse this.
Besides... A set of .100+ 2.020/1.60 chev valves cost a whole $120 and opening the guides and VJ on int's would only cost another $245 and heck you could breath on these RHS's with a grinder and have bitchin #'s.


Read all of the thread/s 1st.

LOL i absolutly loveeee the fact that YOU think you know what IM running...great for maddart that hes doing more than me...until i see proof that these heads perform up to snuff with dyno numbers or timeslips, then i will hold my point of view that they are not worth the work involved to run a high lift cam...I am not vouching for any set of heads over another, but i do believe that right now these heads obviously havent had enough run time yet to see what they can do...we need guinea pigs and i guess maddart is one of them (and i applaud him for it too)...i am currently not running a high lift cam, but i plan to do a cam and head swap, with a cam ATLEAST in the 550 lift range...so how about you dont confuse? lol
