Default Bigger valve cover problems ... help?

I went to some bigger valve covers for my Brodix heads, and now the A/C compressor needed to be spaced out 3/4" on the bracket. Now I realized the stock belt won't fit. What size belt do I need? (1" longer?) Anyone know?

I also need to modify the wiper motor ... can anyone give me some tips? Pics?

Thanks.

I went through that awhile back on my 85 and on the wiper motor I had to trim the plastic cover and remove the washers between the motor and the firewall and it cleared...barely. On the A/C compressor though I didn't have any problems so I can't help you there. Good Luck

Anyone else have these problems when going to larger valve covers?

Do you have any pics of the modified wiper motor?

I don't want to change my valve covers, I was hoping to just trim the plastic on my wiper motor. Anyone else do this mod?

What about the belt length?

There are a few rubber gromits that you can take of that will give you a little more room..3 total.

After removing the gromits and spacers, how do you trim the plastic wiper motor cover? Does it need to be recovered? Pics please?

Previous owner modified my wipermotor by swinging a 500lb piece of iron at it. :jester

It's not very pretty.

Well if it's an emergency you could attack the corner of the wipermotor with a Dremel w/ a cutoff tool. You'd gain the clearance and the cut would be clean but it doesn't look that cool.

I don't know what your setup is but do you really NEED tall covers? I've got a one-piece seal block and heads in my car and I fit aluminum roller rockers with polylocks under some cast aluminum valvecovers. Seems to me a tall valvecover shouldn't be needed unless you're running girdles on the rocker studs. Just a thought.
