Stage 2 ARP head bolts

I bought the ARP head bolt kit for my heads but the Stage 2 heads take 3 smaller size bolts.

Does anyone know what size they are or the part number from ARP?

Thanks Joe

 

I just drilled my block for the TA Stage 2 SE heads outboard holes. They are 3/8-16 NC .

I purchased the TA 1131 head stud kit and it has the correct studs for the extra holes.

Not sure what the ARP 3/8 studs alone would be, but I am sure Mike or Tim could tell you.

 

TrunkMonkey thanks for the response. I was actually wanting to know what size the shorter ones were in the heads not the 4 really small ones at the edge.

It's really just the length that I'm needing.

 

2-1/4" and 2-3/4 inch

Is this what you needed?

 

Michael thats exactly what I needed. Thank you very much....

Hey Big Joe,
Have you made any progress on putting a Buick engine in your 49 Chevy?
I have a 54 five window 3100 and I’m doing a tubbed and narrowed 9” Ford with four link ladder bar suspension. I’m definitely going Buick but I haven’t decided on big block or small block with twin turbos or maybe a procharger.
I’d love to see some pics of yours or even just a progress update.

Good Luck with everything!!
