What do you guys think would be a better choice for my car, the edelbrocks or the x heads? I currently have an LD 340 intake, Comp XE268 cam, Hooker competition headers with 2.5" exhaust, thermoquad carburetor and low compression 340. Would the power gained by the Edelbrock's be worth the $1400 for the heads? I'm on a tight budget so I don't want to spend the money if the gain wont be worthwhile. I dont have either set of heads right now so I'll be getting a set of either. Im trying to get this car to go 12's if possible.
If your pistons are the factory or factory replacement pistons with the 2 valve reliefs, they are positive deck (out of the bore). You will need to measure piston to head clearance with the edelbrocks because you are going from a open chamber to a closed chamber.
It's a good idea to know the piston to head clearance no matter what piston and head you use. If you can, get .040 to .045 clearance for good quench.
