M&A headbolt PN for 109 Block

[CraigT]

I need the PN for ARP bolts to use M&A heads on a stock block. I ordered the bolts listed for the M&A's but they are for the stage block. PN I ordered is 123-3602.

I put my old M & A heads onto a 109 block this past winter. The heads came off my stage block.

I was able to reuse some of the studs but to find the length of the few I still needed I put a little 90 degree bend onto the end of a wire and stuck it down through the head and deck until it hooked under the threads in the block. Then I measured the wire and added the thickness of a washer and nut and ordered that length directly from ARP.

Dunno if this is the proper way of doing it but it seemed to work.

Could you please post the mesurments you got?

 

[ChrisCairns]

Sorry, I don't have them. Probably just wrote them down on a scrap of paper, ordered the studs, then threw the paper away.

And I ain't removing the studs from the engine to measure them for you.

 

[CraigT]

Do you need the bolt measurements? I can get those for you, Mine are out now.

I have a set of the stag II bolts I orded them by mistake but need the mesuremnts for the bolts to be used on a 109 block with the M&A's

Measurements were taken from under the bolt head without the washer.

Long- 4 3/16
Med- 3 1/4
Short- 3 1/16


Hope that helps.
