Default guide plates

I need to install guide plates for the 1.6 non self aligning roller rockers that I am putting on my heads. Is there any specific kind or style that I need to use for the LT1? I heard some where that my heads may need to be machined if there not the right kind. Some one please dime in on this. I don't want to any extra work unless I have to. Thanks

TrickFlow guideplates work well on my LT1.

Just checked, they have really went up in price! I paid $16 for a set in 2007. They are over $50 now.

Where did you see the $50 price? Im just going to order those. If they worked on your lt1, they should work on my 93 with no problems.

Years ago when they came out with their Twisted Wedge heads for the L98, I had the displeasure of buying their stuff. A month after they were installed, I got a package in the mail from them. Apparently there were QC problems with what I was sent and here is another set.

At this point, their cheap heads helped shoot a good block from LPE. So will I ever use a TFS product? Not if you gave it to me except as a boat anchor.

yes. I'm not going to be racing, but I dont want to take a chance of bending a rod. I will also remeasure to make sure that I have the proper rod length.
