For assurances, what is the ARP Part#?

Longer head bolts if you already have a stock length 145-3606 ARP Hex head bolt kit and just want to buy the ten longer bolts instead of a complete 145-3609 kit are ARP-HAP4500-5

Thank you!

I mocked up the rocker arms with a thick steel hold down and a thick washer and came to the conclusion that a 2.750 long stud would be better.

The Crane rocker arms look like they fit pretty well on these Trick Flow heads.

Different rocker arms on the TF heads:

Good call; you can see minimal threads captured with this setup - top end of studs.

We're all learning together on these...thanks for the additional update!

AndyF,

What is the part number for those rocker cover gaskets. Are those from Felpro?

Moroso makes them. Rubber coated steel. They work really well with a cast valve cover that has a flat rail. About the only gasket that works with a vacuum pump.

I've had no luck with those Moroso gaskets, probably cuz I over-torque them. The Superformance gaskets are 10 times better in my opinion.

ARP part number for the 2.75 long studs should be ARP-AJ2-750-1B

Thanks AndyF!

Has anyone got these heads on a running engine yet? If so whats the verdict.

Mock up with RAS rocker arms:

I just got a set of rocker arms from Hughes so I'll get those installed and snap some pictures. The new Hughes rocker arms look great.

Andy dose RAS still sale those rocker arms and shafts. Looked on there site couldn't find them. Thanks.

No idea. RAS was sold then went out of business and then came back under a different name. The RAS rocker arms used to be the best shaft rocker arm you could buy for a BB Mopar but I don't think they ever sold enough of them to stay in business. I've owned a few sets over the years and always had great luck with them.

We are looking at going for a set of these heads for my sons Aussie A Valiant, it is a mild 440, 11-1, 650 lift solid cam that is currently running my Max port 370cfm SR indys. Have been told that the engine would like the smaller T/F's. Might get my heads back

Hughes rocker arms. This new design looks pretty tough. I like the groove and the beefy design.

^^^Those look nice.
