The Renix 89 head bolts use a 16 mm, 6 point socket. I noticed that Muad'Dib posted using 5/8" 6 point sockets on his 90???
I was looking for an another thread to ask this next question, but this thread will do.
I took the 89 head off and had the local machine shop do their thing. I noticed a couple of curious things when I got it back today. One was it looked too clean. Turns out they painted (aluminum zinc color) it before reinstalling the valves. I asked them how much they took off the head, but they said they did not know exactly. He did say "not a lot". This is an old established racing head shop too! I was not impressed.
Anyway, I followed 5-90s suggestions and pulled the lifter rods (and kept them in order in a box), and I reinstalled the rockers in the their original locations on the head. Took the head to the shop, but when I got the head back the rocker arms, bolts, etc where all loose in box. :scared:So now I have no idea which ones went where.
Is this a problem???? What should I do????
Also I am planning to try and do some sludge cleaning - removal of sludge build up from the top of the 3 front lifters, with out disturbing the lifters. I am thinking of using some MMO and a long handle manual brush or screw driver maybe, and a wet/dry vac to loosen and suck the sludge out of there. Any comments on this plan????
Muad'Dib,
I am thinking of using the locator studs on the front and middle of the block only, leaving room for the rear of the head to go into the tunnel at deep angle, front of the head being the highest, then lower the head at the front side onto the locator studs. Also I had to raise and
duct tape :laugh3: the drivers side rear head bolt to the head and remove them together on this 89, there was no way to remove that head bolt (oops, head screw!, LOL) first, short of droping the engine on the driveway. I am thinking of going back in the same way. What do you think?
Oh, We man handled it coming out, and got real lucky that we did not damage several parts (O2 sensor.....), so I am packing up the engine hoist and taking to the house for the reinstall.

OOPS... One thing i missed:
Im not sure when they changed head bolts, but ive seen this info everywhere.. Its just plainly incorrect for me.
I just wish i could remember what size they ACTUALLY were ...
Oh i have a 90 RENIX... so im not sure if the head bolts changed when they changed to the HO from the RENIX...
