Hi,

I am putting together a 499 cube street stroker motor that should be making about 600hp. Should I be looking at cylinder head studs. I currently am using ARP bolts. Does anyone know the correct part number for studs when using stealth heads or edelbrock RPM heads? I think it's Arp 145-4206.

I would also like to use studs on the rocker shafts. I can't find a kit for these. I think I need to buy individual studs. What are the required lengths I would need?

Hughs Engines has a nice hold down kit with studs, nuts, washers, and billet steel holddowns.
They also have the studs you want. I chose not go with studs on my 493 just because if I needed to remove the heads in the car it would be easier. I used the Manley head bolts that came with my heads.

Gus,

Very good point. I might have to keep using the head bolts. I don't think I can remove the passenger side head when using studs.

I went with bolts as well for this very reason. I need to look into the Hughes rocker hold downs as they look very nice!

Most ARP studs can easily be removed with a 3/16 allen wrench.

My combo is very close to yours; street/strip 499", Edelbrocks, 11:1, flat tappet solid, 520RWHP. Using bolts, not studs for nearly 9 years with no problems.

My 440 running 12.5 domes uses ARP bolts with Stealths.Been on at least 6 years now.Lots of street miles and some 1/4 passes.No problems.Rocky

You might be able to remove the lower heads studs in the car One thing about the head studs and headers is if you have a set of big tube headers the head studs may hit the header flanges , been there done that I run head bolts on my current bracket car because of that issue

Thanks everyone for the great feedback. I will stick with the bolts.
