   Ryan: It may not be necessary for you, with out turning much speed, although the added spring pressure may require stronger pushrods. I use Dodge 225 slat 6 ones that I shorten just a tad. After that I've never bent anymore. The stock pushrods will bend just because sometimes. They were not designed to run at the speeds I'm running or with the boost pressure. With anything, after you go beyond the design tolerance you will find the first weak link. After upgrading that, you will find the next weak link. This is what us tractor pullers are constantly doing.

	If it was fun to pull in LOW gear, I could have a John Deere. If you can't make it GO... make it SHINY

	Thanks Paul, I appreciate the response. Is there enough material to move the pushrod hole over? I understand about the valve springs RPM.s and not needing any of this stuff. The tractor I am working on is not a cream puff, it never will be. Someone with a blow torch loved to use it. Although he did blow a hole through the torque tube to mount a Mopar starter, he used the torch to drill holes, trim small things, make a Frankenstein bracket for the alternator. I have removed some of his handy work. But understand that I am not beating up this tractor anything close to what the torch guy did. I have the time and "some" knowledge to work on this valve trane IF it's possible to move the pushrod holes over without breaking through a water jacket. I was going to just throw the head back on and go but the more I look at the cylinder liners the worse they seem to get..... " border="">

	I have never tried to move the pushrod holes over. I've always found the OEM rockers to do the job intended even with the high RPMs, extra spring pressure and boost that I run. I also feel that steel or iron rockers are superior and durable to aluminum for anything other than extreme (10,000+) RPM. I have enlarged the holes on some heads to used the larger Dodge pushrods and not had a problem for what was need to stop rubbing.
