It changed in late '05/early '06. They added more material around the injector bungs.

Re: When did the HSR change??
Can't help you with when they changed it, but yes, they did make them back in 02. That's when the one in the top of this pic was made, the bottom one was made in 07.

If you happen to get the one with less material, there are always fixes...

Re: When did the HSR change??
i'd just be worried about warping the face of the intake manifold. i'd definately would like to have a 406 + inch HSR motor with 215+ cc heads. i'd need material welded on

Re: When did the HSR change??
Yeah I know what you mean. I had my planed after the extra material was welded on, just to insure that it would still seal properly. Didnt have much taken off, and the gasket was thick enough to offset it..
