Finished assemblied BB , was getting pushrod length ,got my pushrods ,look good ,but have a clearance problem on pushrod hole at top ,How are you guys clearancing these ,die grinder ,redrilling hole bigger Etc ,Are you pulling heads or just covering valley and getting after it ,any input would be grat ,thanks

Die grinder with a rasp file but dam hard to do on the car!! I would pull them off the head gaskets will be fine.


If it just in the hole a drill will probably work??
take em off the crap gets everywhere.

Its still on the engine stand ,its got one of those 440 source valley plates that doesn,t come off without pulling head ,just looking for some ideas ,thanks

I don't know but it is real hard to not get shavings down in the engine!!
If you did not have that valley plate you could use a vacuum below the pushrod hole!!

I had the same problem. I offset the rockers with a .015 shim. You may have to sand down the sides of your hold downs to offset the rockers. Just keep an eye on how the rocker is lining up with the valve. Dont offset it to far, just enough to clear the head . 015 -.020 clearance between pushrod and head should be ok.

I looked at them real hard ,they are inconsistent ,some are rubbing on side ,some on top of hole ,i am going to pull the heads and put them in a bridgeport and drill them bigger,i would think edelbrock would have give us a little more room here ,i keep looking at my pushrods size ,i,m thinking they are 11/32 ,going back to 5/16 might help ,but i don,t think it will solve the problem

I feel you pain when I bought my Indy SR's i had them all torqued on then found the pushrod holes were not big enough. now if I get my hands on any aluminum heads I open the holes up before even a test fit!
You learn after a while!
