Anybody ever drilled spark plug holes in the right side of the heads to create dual spark heads? If so, did you gain anything from it?

Also, I am considering having the rocker arms milled for roller bearings.

Anybody ever done that?

Please advice.

Karthy,

Why would one do those things to such an old engine. Mine is a 1970 Ironhead and I am just trying to keep it going. A lot of parts are nolonger available and very few performance stuff. On my bike, the engine casings are no longer available and if they get damaged, I get to throw the engine/bike away.

I would suggest if you want high performance, get a newer engine where parts are available and you have a good choice of performance parts. Otherwise just keep the old bike running good.

hi karthy,

Personally, I wouldn't do such a thing to an ironhead. If I were to do it, i buy a new engine and then only after extensive other modifications were completed. I'm not an expert but, I don't think the benefits are that substantial, as compared to alot of other modifications you could do.
