Edelbrock / RHS heads, or go BIG block and put it to bed!

No issues with the aluminum I've ever heard about. Some casting core shift issues that pop up occasionally but that's fairly rare. The finish machining is not that good but the gasket matching takes care of that. Not even close to the issues that the W5s had. First set was used in 2003. The valve jobs never improved...lol.

Well this is what I seen posted on another forum and Joe SHERMAN RACING agree with the dudes post. Joe is an old man now, in his 70's, been doing this all his life. Posts are 5 years ago but what has been getting better since then--nothing, lol Again I'm not spending my money on Eddie heads, not when there are other heads to buy...........................................................................................................................http://forums.corral.net/forums/5-0...oved-edelbrock-60379-heads-afr-165-heads.html

If you are worried about stripping the threads in aluminum heads, you may want to have a pro do the installation.

The OEM does not used Helicoils in their heads and for years they've never pulled a thread.

I will tell you most of the reason Edelbrock "has to" put Helicoils in their heads. It's because the raw material used in their castings is poor, very poor quality. Many times I've had to weld up pin holes and porosity issues when rebuilding these heads. I'd be surprised if the base aluminum casting could hold any torque at all!
