Will these valve covers fit?
Any one ever used the Proform 141-261 or GMPP 1915-6429 valve covers? Wondering if these will fit an otherwise stock LS7 without hitting the alternator.
Proform 141-261
Gmpp 1915- 6429

Don't know, but wondering where you are putting the coils when you change over?

Alternator grinding IS required. Ask me how I know. They are definitely not plug-n-play on our LS7. The finished product looks great though, very happy with the results.

^^^Nice!
So where and how much did you have to grind? I've got all kinds of grinders and saws, not afraid to remove a little metal.
What coil brackets are those BTW?

Get Proform's coil relocation kit too. It's made to work with their valve covers. Proform makes the covers for GM too.

I have the Gmpp 1915- 6429 w/the extra thick VC gaskets from Yella Terra YT 5132. I used Katechs old style coil mounts. I drilled and tapped the VC for the mounting bolts. I put a dab of ultra black on the holes. The holes go into the baffled area of the cover.
The polished VCs aren't clear coated and will tarnish if not kept up on regularly. I eventually painted them black wrinkle . Katech/MSD wires or Crane truck wires will fit

Hey Mark, they're polished aluminum from Billet Custom Products, a board vendor. Very nice quality but not cheap.
You can email them @ sales@billetcustomproducts.com

With the GMPP covers and thick gaskets how much, if any, did you have to remove from the alternator?
How did you do the breather hose hookups?

You are going to drop some pretty good coin going to the Katech kit. Although they do look good. Here is a cheaper option, $299 from Holley, and then modify your FRC's to cover up the injectors and wiring:

Another nice one. How did you get the nice straight cut in the plastic covers? Table saw?

If you look at the pic in the first thread there is a small nipple on the left side similar to the factory. Use a rubber right angle nipple
I don't have any clear pics to show it, sorry
Not aware of any others that have these on both covers, and baffled, that's why I used these, and they are slightly taller about 1/4"
They come with a chromed cover with the Chevrolet script, Polished only with Corvette in black or red script, GM Performance Part Logo lsX polished and no logos on polished cover
See your GMPP dealer or favorite vendor ----- This has been a Film Ways Presentation

Good info, thanks.
Looks like at least 5 ways to go, all look good, which one to choose? Decisions, decisions...
