Paul, Seems like every set of "no-name" aluminum heads I get in the shop have the guides totally killed. I suppose it could be valve train geometry and set up causing it but its funny that I rarely see a set of Brodix, AFR's etc like that. What do the valve stems look like on dissasembly? Are the v...

Paul,

I use them almost every day. That is all I have had for the 30 years I have been in business other than the Serdi type cutters for my TCM 25 seat and guide machine. I use the Neways for just about every stock valve job that I do. I do have the stands and the electric drive setup. I find them very fa...

Blocks or heads ? I would call someone like World Products and see if they will sell you bare castings ? Maybe Dart or Edelbrock for aluminum ?

Looks almost identical to the BHJ one that I have.

Post and Poster, have been deleted.

To report a post, click on the square with the “!” In it, in the upper right hand side of the post

Doh ! Probably the only thing I didn't try

Are you asking if you can use the LS locks with the square groove valves ?? I would probably say no since the LS locks are round groove.

I thought there was a way to "report" a thread but I cant seem to find it. Anyway this one needs to go:

Try turning off the rev limiter and shifting at 6100 manually ? See if the engine will go to 6100 that way. Thanks Bill, I tried that and it would not go past about 6000 according to the tach. It acts like the HEI rev limiter is set on 6000 when it is set on 6400. Well that certainly sounds like a ...

I fabricated reamer center cones that center on the valve seat. Reamers coming tomorrow. Not sure if that is a good idea or not ?? The reamer is probably going to follow the guide no matter what and if you try to force it off to one side with the cone it is liable to end up making an oblong hole ? ...

I plan on baking the head in 400F oven

That should ruin it real good

I never go over about 160 degrees and put the guides in the freezer and they go right in. I use some CMD Extreme Pressure Lube in the guide bores.

Hi BIll, I'm considering AERA. Other than resurfacing heads for local shops, I only do engine rebuilding for myself. There might not be much use of the services for me. Although the spec manuals that come with joining looks to be well worth the price. ……..I just joined. Mark Mark, I simply cannot i...

What would be the best way to attack narrowing the current seat? It seems I could carefully adjust the 1.5 cutter to meet up with the 30/45 angle, then I think the 60 cut in until the cutter just touches the 30/45. Depending on where the seat is hitting the valve you might just be able to go in wit...

Ok, Oil ring looks fine :) Must have been the angle in the other pic. The main bearing looks like it is contacting almost 100% of the bearing diameter. Usually there is an area near the parting lines where the bearing is thinner and there is no contact. I think Clevite says it should be about 80% co...
