If there is a better stock gasket I wouldn't know what brand it would be. The ultimate fix is to use wire rings from DQM or whatever it's called now. .105" diameter wire and if you are using stock sleeves go with a 4.650" O.D. on the rings. To do this the flange on the sleeve much be faced of about .033" for proper fit. In conjunction with these rings you can use the stock gasket with the OEM fire rings removed or use a copper gasket which is reusable many times over.

Another option may be to just use a copper gasket with the correct bore size. It may squeak a little compression when cold but it won't blow out. You will have to have adequate sleeve stand out for this to work.

Call Robert Alves. He makes a nice copper gasket at a reasonable price.

Well my crystal ball is broke down today. I would guess you can use it for a while but it will eventually leave go. What are you using now and is it blown out or are you having good luck with it? If it's working stay the course. If it ain't working doing the same thing again will most likely end up with the same results.

I don't have it together waiting for rods to come back from heat treating. I was wondering whether the stock head gasket would work with hx 35. Just trying to eliminate any problems

If you don't have the engine together I would machine the sleeves and use the wire rings and a copper gasket. This combo will put up with a lot of horsepower. The initial price of the gasket will be higher than a paper gasket, but if you re use the gasket twice you will more than recover the cost. You should get 6 - 8 uses or more from the gasket. The wire rings are cheap at about $85.00 for a minimum order of a qty. of 18. If you do this and do it correctly, you will not have head gasket issues and in the long run it will be cheaper. You could have the copper gasket and the wire rings within the next couple of weeks I would guess. If you need dimensions of the gasket, sleeve flange, or wire rings let me know.

You are thinking correctly by doing it right the first time and avoiding problems.

Have you tried the HX35 yet and if so, how does it work?

The place that makes the seal rings is Seal-Tec 630-692-0633. They are in Oswego IL. You have to tell them what you want made, they don't have application info. If you prefer, I can buy them, and sell you the 6 you need. The price has gone up some, and I try to keep the ones for a 426 that are drop on, as well as machined sleeve size. If you have the right info, you can have a size made that won't require machining the sleeve, but aren't as tough as the thicker ones requiring sleeve removal and machining. The level you're looking at, I would feel comfortable with the drop on. PM me for more details.

Don't forget too much pump timing on a 301 will kill stock rods and head gaskets too. There is a point with pump timing where no power is gained. Retard two degrees from that point.

When pump was build they had said to put it at 35 degrees an advanced was locked.
Will it hurt anything to run less timing.

Timing is one of those things, that if a little is better, a lot more isn't better. 32 to 34 degrees on a 301 is usually best.

You asked about head bolt STUDS. I know of many diesel 301's that run 100 to 110 lbs all the time with regular A-C head bolts. I know of one that used to run 140 psi boost with three turbo's that had A-C head bolts. Whatever you're thinking, studs won't fix a head gasket problem on an A-C.

40 psi with or without studs is pretty close.

Head studs on a 301 are not necessary and would be a waste of time and money.

I realize you are trying to avoid problems down the road which is good. With that said, if the engine is already assembled I would run what you have until it blows. When it does, fix it. Blowing a head gasket won't hurt the engine any.

A 301 with stock conn rods just might bend a rod before it blows a head gasket. Ain't that right Robert C!!

Skip that HX35 put on an h1e holset and kick some, h1e open rpm 22 exhaust housing,Vogel cam ,water and intercooler will get you 500 horses at 60 lbs of boost. One nasty little turbo 2.37x2.67 I think.

You are correct for open RPM 301. He is limited to 3,000 RPM with no cooler and a small output injection pump. The HX40 is the newer version of the H1e and would be better yet for open RPM.

My mistake. His is running open RPM I think with a cast flywheel and P.D. clutch. He should be running no more than 3,000 unless those are changed.

Point is, I think a 301 with a 250 cc pump @ 3K RPM won't spin an H1E / HX40 where a H1C / HX35 might work better.

So can you run open RPM? Good to hear about the flywheel and clutch. Have you done any port work to your cylinder head? Also, can you run an intercooler? Lastly, what exhaust housing does your HX35 have on it?

As far as 7th gear @ 8500 lbs. you won't do it without a DB .450 pump. It sounds like you may have a flywheel clutch that will do the job (if it is a multi disk), but the PD clutch will have to be removed. It will slip if you ever get enough power to run 7th gear weighing that much. D19 low side PD gears will slow 7th gear down by about 8%. Still will need a bigger injection pump than your .390.
