318 Head Opinions

I never seen or heard of many people at all doing the off set grinding crank trick. Theres actually a thread here on doing just that somewhere.

Theres also a few on stroker on the cheap. Reuseing stock pistons in such applications as well.

So a cam with .480 lift in a teen is quite a large cam,but not so with a 360.The smaller bore may contribute to this.So for a teen,less is more.

I'm not so worried about the bore size or valve shrouding but the cam size is fairly moderate large size for the teen. I had an arguement with a fella once on this were I didn't really like this cam in a teen with his proposed 3.55's. I thought it to steep. Even with a converter to help it out alot, his balance was off and ears closed.

Stock Magnums do not flow so great. Not bad, but not great. $500 for a rebuilt set is OK and nothing I would jump about. X and J heads are also found rebuilt for this and port well also. Granted, not as good as the Magnum, but the additinal cost of converion hinders most.
Ya kind of gotta want to do it. As much as I could point to this head being better, for some people, an extra 1 or 2 hundered is alot. Therein is the reason for building what you got.
