| Message | diameter studs?  I know that the multi-layer cometics need to be machined to accomadate larger 1/2" studs on SR's, so I assume something needs to be done for your headgasket??? Also, do you think there is enough material around the larger  9/16's tapped hole?  Could you helicoil the hole to have a greater bite in the block??? Finally, will the 9/16's washers fit in the heads recessed seat or do these need to be bored to a larger diameter. Thanks
