Valve covers for trickflow heads
I am in the market for some valve covers for my big block RB 440. I currently have trickflow heads installed.
I currently have the cast mopar performance valve covers. The trouble is they do not fit well on the heads and they leak because they are wider that the rails on the heads.
I was reading on the 440 source website where they explained part of the problem.
“Most aftermarket aluminum heads (including our Stealth heads, Trick Flow, Edelbrock and others) drill the valve cover bolts perpendicular to the rail. If you are planning on using these valve covers with aftermarket heads, you would need to install studs, and then bend the studs very slightly after installation so they align with the angle of the valve cover holes.”
I wonder if the trickflow valve covers or some other ones fit their heads without mods or bending fasteners, because all I see happening as I am bending the studs is cracking the bosses on the heads.
