so i have the mods in sig, when i got the motor together i had a horrible "lifter tick" that i could not get rid of, i tried adjusting the valves multiple times and the noise got better and worse each time, i also rechecked the pushrod length and that was fine

finally i started pulling everything apart and when i removed the guidplates i noticed the back side of the guidplates were wearing pretty bad but only the back three on the passenger side of the motor, so i showed my buddy who ownes the local machine shop and we decided that the best thing to do would be to "end mill" the inside of the guidplates to make more room on the back side

well i got it all together today and the problem is fixed now, just wanted to post this to see if anyone else had a problem with these and to put this info out there incase anyone runs into this

Thanks for the heads up... I am currently looking at interference from between my pushrods and cylinder heads on two cylinders on each side. Intake cylinders 2 and 6, exhaust on driver's side (can't remember which two). Are your LE2 heads GM heads that are modified, or are they aftermarket and modified?

I run TF plates, I took a 4 inch grinder to mine. The pushrods would have hit if I hadnt.

pics of what you're mod is before/after since its a little hard to visualize?

Hopefully you didn't go thru the case hardening on the guideplates with the end mill. That would not be a good thing and could easily eat up a pushrod or the rest of the guideplate. One of the many reasons I use the Isky Adjustable Guideplates instead.

BTW what's up Josh? I've been MIA lately in the shop

I will get some pics up in a little bit. I wasn't smart enough to think to take pics while I was taking the driver's side head off, but got some on the passenger side.

stock heads ported

well the part that was milled should not be contacting the pushrod at all, i know its hard with out pics but visualize a U that is the inside of the guideplate, the bottom of the U is where it was contacting and where was milled

but thanks for the input bret

Nada been spending too much time at siu, I got the 440 mopar with efi together and on the road, pm me which email you check regularly and i'll send you some shots of it. first time at the track it lunched the 4 speed so we put a tko-600 in it then it fragged the drive shaft, the next week it fragged the rear, the owner is out of money for now though so its shelved until next season. Which is fine because thermo is kickin my ***.
