Roller rocker arms and valve seals - ideas?

Bill, I think that you may be using these and so may Shawn and Shannon, so I'm looking for advice. What ratio do you guys recommend for a stock engine like mine, with just headers and soon to be installed tri-carbs? Where did you purchase yours?

I'd like to get it to breathe in and out a little better now that I'm adding more fuel to the mix.

Also, I think that my newly found oil consumption issues (since I added the auxiliary line to the head) can be solved with valve seals. Anyone using them at this time? If so, where did you get them and are they still available?

Anyone else with advice, please chime in. I just asked the usual suspects because I thought that they were already using the setup.

Thanks in advance,
 
Paul, the fella that redid my head installed new valve seals for me (Bill Crosby at cdamachine.com).

You are getting awfully close to finishing the job. That is, shave your head and put in a GP2 cam. I took exactly the steps you are taking, in that order. I finally dove in and finished the job. Glad I did.
 
Bill, I'm getting even closer to Rhode Island District Court, where the majority of the divorce cases are heard. If I shave the head then I'll want to do the bottom end. Then it will be pistons, crank polishing, line bore, ya-da, ya-da. If I attempt to pull the engine this year, I won't even be able to sleep in the garage, because that will require living in the house, which I will no longer be doing at that point.

However, you do have a very good point there and perhaps I can use my famous "it's for the yearly maintenance, safety and reliability of the car that I do these things" line one more time. It just won't be this year.

Think you could ask that guy where I could buy the proper valve seals to fit my TR6? I can do those myself as soon as it gets warm enough to work in my new bedroom.
 
Paul,

This is the same route that I went down as well. As Bill suggested, one mod does indeed go hand in hand with the other.

The best mods you can do to these motors IMO is to increase the compression to 9.5:1 - 10.0:1, and install a nice street cam. The roller rockers are kinda the icing on the cake, but they won't make near the difference as the cam and compression. The next best would be an aluminum flywheel, but I wouldn't install one of those without a balanced assembly.

I'm running the GP2 cam, 10:1 compression, 1.55 rollers and an aluminum flywheel. I absolutely love the setup; very strong, smooth and very, very street-able.

As long as your block is pulling good compression and the end float is within spec, there is really no reason to pull the motor.

My advice... pull the head, shave it, and install a cam and new seals. The rockers cam be done later if money is an object (could be installed in 3-4 hours).

Rebuild the short block next year run the heck out of it this summer!
 
Call him Paul, he is a nice guy. Knows a lot about racing LBCs. I believe we got my seals from Richard Good, at my request.
 
I'm going to sign off now. You guys are hazardous to my health.....

Thanks and you know that I'm giving it serious thought.
 
Paul, I'm using 1.55:1 roller rockers as well. Richard Good told me that you don't want to use his 1.65:1's without line boring the block and installing cam bearings due to the increased spring pressure on the cam, they can otherwise cause accelerated camshaft wear. You can get by without the bearings on the 1.55's if the block journals are in good shape.
 
Email conversations are ongoing with Richard Good at this time.

More to follow........
 
Wow, you guys are talking about some really
interesting upgrades.

I am hoping this year will see Crypty
"upgraded" to operational status. I'd be
happy for a 6 mile drive without a breakdown
then followed by months of repair efforts.

I guess I am using Pedro valve seals and
Pedro cam bearing!! Probably very reliable.

More snow and ice in the NE-- poor SOBs.

OK, Dale, enough about the snow. Besides it's just cold rain now, with ice to come this evening, so don't exagerate the conditions.

Man this does suck, but it's better than 12 feet of snow like those poor guys in Oswego, NY.
 
you know after 5-6 feet of snow it doesn't make much diff.

wow, I might even have to lock my diff on my cruiser for the first time today to get up my driveway.

right now 3-5" of wet stuff in boston with a ice mix. They say 6-10 at my house & then rain/sleet/ice later.

Gonna blow off work a little early to get my tractor running to plow off the heavy stuff.
 
I can't see my lawn, but I do need to get some more wood in for the woodstove though.... No wet stuff, just pure sleet snow mix. It stings pretty well with the wind kicking up...

There's something wrong here. I have a perfectly running TR6 and can't drive it because of the weather. Bill and Dale have perfect weather, but torn apart TR6's. We need some sort of a swap.
 
Paul,

I'm happy to help you out

Remember where you shipped the driveshaft?
Ship your yellow TR to the same address
and I'll ship you a red, in parts, TR to play
with over the cold, winter months.

That wasn't exactly the swap that I had in mind.........

Besides, it's too cold to work in my garage.

Nice try though!
 
Fortunately I do have a heated garage and I hope to do some work on the gt6 tonight.... One could see that one coming Paul, snowstorm or not... ;-)

Dennis
 
Yes, Dennis, I did set myself up for that one. And of course, my Apprentice Tech #1 down in sunny Puerto Rico, jumped all over it.
