SignUp Now!i got a set of these from Weber Racing.. but this part # comes up for a Stage II and the gaskets have the extra head bolt holes.. Is this normal?
I requested that SCE deleted the non used holes on mine.
Just changed mine to cometics from the same thing as Dusty and cdsttype just described. Egg shaped #3,5,& 4 cylinders using the 3 extra studs across the top like KevinB has and RJC's head clamps across the bottom on TA aluminum heads. I'm almost sure it's from the copper being to soft.
3 extra studs across the top on a 109?? Please explain or show me pictures!!!:biggrin:
Yep they've been doing that for some time now. How do you think Dick K keeps his heads on 9.16 TSM and the 8sec pass.![]()
id like to see how this is done also..3 extra studs across the top on a 109?? Please explain or show me pictures!!!:biggrin:

My block is not a 109 so it had a little wider deck across the top for room to drill and tap the 3 top ones. I just had a welder build up the block above the area were the holes were tapped to give a little reinforcement. Head clamps across the bottom and 60lb's of torque on the 3 extra bolts seem to be working good with cometics for my set up but the SCE ICS Titans egged shaped on a few cylinders.
I wonder if a 109 has enough girth for the extra? Im not against welding it to work
