Alumiumn Heads Question?
Just got my heads in yesterday and have a few questions.
1. I noticed a little flasing on some of the Exhast ports. Is it alright to remove this with a grinder?
2. I was told to use a sealeant on the rocker arm studs. Will permatex be ok for this?
3. Will my ARP head bolts work with the Alum. Heads? Corosion? (Steel/Alum)
4. Anything Else I might need to know before, during or after I put these on?
Thanks..

1: Yep, removing it is fine.
2: I use RTV black. I'm sure permatex is ok also.
3: ARP steel bolts work fine as long as they have the hardened washers. Without washers you will gauge the aluminum.

1. IMO OK to remove excess flashing only, don't alter the port wall contour/size
2. Permatex OK.
3. Steel bolts OK. Not aware of any alternative anyway ... besides titanium or the like.
4. Follow torque sequence & specs. Use head gasket that won't score head to block surface. Apply small amount of lube under bolt heads to avoid scoring head surface and to obtain accurate torque reading. I think ARP bolts are washerless.

Re: Alumiumn Heads Question? (mdsmith)
Thanks for the replies. I was thinking of using a fine file to remove the flashing and be real careful. :eek: The ARP bolts that I have do have a washer. I also have to use antiseize on anthing that screws into the heads also correct? :yesnod:
Thanks again. Maybe I can get pictures by monday. They sure do look :cool:

Use a copper crush ring head gasket for aluminum heads. I put thread sealer on every head bolt or stud. Invest in ARP header studs and install them with anti-seize. Never take a chance on stripping out a threaded hole.

The ARP bolts that I bought have a thick washer under the head. I used the black Permatex RTV.

The Fel_Pro you want to use is part number FPP-1010 in the Summit Racing cat.
I'm using something simular, but I got it for a 4.030 bore to keep compression up.

Re: Alumiumn Heads Question? (gkull)
Thanks for the heads up on the gasket. Apperently the heads require a :eek: Performance Gasket :eek: for both the heads and intake. Call my supplier and the researched and laid out the required gaskets. Still on for tomorrow..
that saved me from a lot of greif :yesnod:

I think the rocker arm stud torque is around 40 to 45 foot pounds.
I had Edlelbrock aluminum heads, and I blended and smoothed out the exhaust port openings, and blended the intake openings. They were CNC'd in only part of the way. Use washers under the head bolts, and use a sealer on them. Also, check the position of the guide plates after tightening the rocker studs.
