Re: Question about replacement seat ID profiles

derek, I think the tapered seats are just to help match the oem profile. As far as the depth you are probably correct but you have to know if you can cut the head that deep and not get into or close to a water area. That is the reason some seats listed are a lot shallower than others. If you have an...

Re: Pick a head, any head.

I am curious exactly what it is you dont like about the performance ? If you had never seen the dyno numbers what would you say was wrong with the way it runs now ?

Re: Driven break in oil

Gary, I have used it in a couple of flat tappet engines and have never had an issue. Try to get my customers to buy it for things they are building. Not sure if I would leave it in for Dyno flogging or racing. I have always broken the engine in easy and then changed the oil and cut open the filter b...

Re: Offenhauser intake manifolds

I’ll be using one, although it’s not a run of the mill 4bbl intake. Crossram setup with Holley efi. I have a 67 camaro and wanted the trans am look. https://i.imgur.com/iZpycxs.jpg A few years ago I had one of those manifolds here and was thinking it would be neat to use the Holley carbs as air val...

Re: Offenhauser intake manifolds

I had one of their "360" manifolds on my Small Block Chevelle a looooong ( 1973 or so ?) time ago and it worked fine for a street engine. I switched to an Edelbrock when I went from the Q-jet to a Holley. I would bet that in 99% or street engines most guys would never be able to feel a difference be...

Re: distributor looens up

Pull the distributor out and then put it back in with no gasket under it. If it goes all the way down and hits the intake manifold then it is not bottoming out. When it "moves" is the hold down bolt loose ? Any chance the bolt is bottoming out or the hold down you have is not formed properly and not...

Re: Press Pins and Balance

HR, The press fit is around .001- .0015 On my Sunnen pin press the gauge usually goes up to about 3-4 tons before they break loose. When I have a set I need to take off for the purpose you are describing, I give them to a friend who has the OTC fixture that goes inside the piston and supports the ro...

Re: Heavy carbon buildup removal

Travis,
On the Chevy intakes I have found that if you get a real small chisel or sharpened screwdriver under the corner of the rivet or the sheet metal you can usually pry the rivets out. Then after cleaning I just tap the holes and use a small screw to hold the shield in place.

Re: Sbc leakdown test reveals leak to ARP studs threads

I can't recall any HG ever leaking/blowing towards the fastener, and having this on multiple cyls proves the point. Live with it, replace the block, or some magic stuff on threads - remove'm one at a time - clean inside & out - thread lock, stud mount, whatever, then re-torque. Forget the waterjack...

Re: Sbc leakdown test reveals leak to ARP studs threads

Some of the replies are talking about sealing the threads but in this case that has nothing to do with it. You are leaking from the combustion chamber to the studs. Only thing that can do that is the head gasket unless there is a crack. What I would do is go around the head bolt sequence and one at ...

Re: RHS 200cc iron heads with 50cc chambers

Can you borrow a couple of valves to get an initial measurement ? Thats what I would do but I have a ton of valves sitting around to try. Would be annoyed if I took somebody's word for it and ordered valves and then had to return them fir the correct ones.

Re: Harley sportster/evo lifters?

K,
If they are the lifters that look like a Chevy Hydraulic roller lifter I have one customer that uses the Chevy lifters and has had no issues even with some fairly big cams. I have been getting him the ones from E-loy. Part number is VL115

PBM Performance has 2 sets of the Clevite MS771G .010 in stock. If you don't have an account with them I could get them to drop ship a set to you.

Re: Man, it smells - Just the nature of the beast?

Without being there its hard to say but a lot of younger guys have never had to experience how the cars of the 60's and 70's ran as far as emissions go. It was pretty normal for cars to run pretty rich and stink the place up, especially when cold. I would try loosening the choke up so it is not clos...
