Felpro 1027 & Brodix RR-R

I have 2 questions, does the 1027 gasket have an upside? I noticed between the outer to inner cylinders the steel on one side is 1 piece and on the other side it all looks the same, right now I have the side with an imprint of a bolt facing up and my 294 RR-R are 115 cc chamber size and where the dowel would go into the head is shaved down now, I'm using ARP head studs so are the dowels important or needed anymore? TIA, rick.
P.S. does it matter if only 4 studs are in for alighning the head then install the rest after the head is on? seems easier but I know easier isn't always better and I'm using Permatex High Tack for thread sealer, is that OK stuff? I have Permatex 300 and #1, dozen rolls of Teflon tape and Teflon paste, engine wont be ran for another month or so so plenty of time for sealer to cure, now that I'm looking at the pic does the HG look like it slid down?

Re: Felpro 1027 & Brodix RR-R

The head aligns on the dowels in the deck, so actually you should be able to set the head on the block with no studs, then screw studs in.

I don't think that gasket matters as far as what side is down, I always put it on like in your pic. High Tack should be fine on the threads as long as the block threads are in good shape and everything is clean. Some engine builders use yellow 3M gorilla snot on studs, some use High Tack, some use teflon dope and tape, some just teflon tape. I'm partial to yellow 3M on bolts or studs myself, but I have used High Tack on them before without any problems. And with studs, also like to drop a stop-leak tablet (can't remember proper name! we get them at Napa) in the water jackets before firing it up just in case a stud wants to try any of that leaking funny business.

Re: Felpro 1027 & Brodix RR-R

Big block head gaskets can only go on one way because of the bolt pattern. One side will be upside down compared to the other.

I dont think Hi Tack really is really designed to be a thread sealer but there are guys that use it. I would use a white teflon thread sealer paste. Permatex has it as does others.

When I use head studs I like to put some sealer in the actual holes before I thread the stud in. That seems to help seal them better than just putting it on the threads of the studs. That's hard to do after the head is on. Also you don't want the studs real tight in the block. Hand tight and then back them off a half turn or so.

Re: Felpro 1027 & Brodix RR-R

I would use the dowels, and the gasket can only go on one way. Those heads are going to be a PITA if you ever have to remove them in the car. So at least if the dowels are there not only for alignment, they will also support the heads while you pull all the studs out to get the head off in the car.

Most has already been stated above but here's my take
Gaskets only go one way or the bores will not line up.
You must use the dowels to align the gaskets & the heads are not milled anywhere near enough to make a difference the correct dowel will work just fine
Studs can be a pain in the ass in a wet deck block. People use all kinds of stuff from the white Teflon to RTV with varying results
I have had the best results with Hylomar sealant on studs & you must let the solvents dry before installing the studs.
In lieu of that I would use Permatex Hi Performance thread sealant
I agree with putting one of the sealing tabs in each bank it should dry up any leakers
Do not even consider using Teflon tape...........

I pulled the head off and found the gasket can't be flipped 😁 then tried removing valve springs with my lever tool and no good so going to borrow a real valve spring tool from my mech freind and dowels fit fine I was thinking they went in a diff spot 👍

Re: Felpro 1027 & Brodix RR-R

I was able to remove the exh. spring by putting 4 pioneer head bolt washers I had under the rocker stud to give it more height, int. I used a 24" bar clamp to help release tension but I'll be using a real spring compressor to reinstall, I still need to set up my dial indicator, check geometry and start measuring for push rods, got a call and had to go back to work so hopefully back at it later today, I also put 4 head bolt washers under the int. stud, I'll post a pic of ARP vs Pioneer head bolt washers, big difference and I did see what Kevin was talking about being the threads in the head aren't very long so wondering why put a stud with longer base threads in? looks like exh. carbon would build up on the threads and make the studs hard to remove if ever needed and slow exh. flow?? I'll have to look at that again maybe it was int. side?

You will wear the valve guides out in short order with those rockers on those heads.

Re: Felpro 1027 & Brodix RR-R

After the guides go out and the hotrod needs to be repaired you going to empty the wallet for around $1200 in parts and labor.
