Does anyone have any advice or even pictures of them bolted in I dont quite understand the instructions that were sent. It was just a diagram that show the bottom (gasket) side of the head and says "drill hole here" Are you supposed to drill threw the lumps and tap the head or what? I am lost! Thanks | | |

It is going to take some gonads to mill that head bolt boss outta the way! I have been tempted to do that with my 292 project as well. Hurry up and get it done so I can hear and see (take lots of pictures) how it is done  | | | | | Joined: Apr 2002 Posts: 1,571 Shop Shark | | Shop Shark Joined: Apr 2002 Posts: 1,571 | I'm with Ken - I've been debating whether or not I want to do this to my 250. I'm already going to have a machining bill for the screw-in rocker studs and oversize springs, and I'm considering bigger valves. The lumps would be nice addition to the mix.
If you ordered them from PES, how much did they cost? | | | | | | Anonymous Unregistered | | Anonymous Unregistered | I ordered mine today. They were $66 + about $8 shipping. | | | | | Joined: Feb 2004 Posts: 10 Member | | Member Joined: Feb 2004 Posts: 10 | Hi guys, Sorry it has taken so long for me to reply I was in LA at Speed-O-Motive dropping off my connecting rods this weekend great place. I did order from PES I have already cut out my bosses and the plates will go in but I am not sure how to bolt them down with the little bolts that came with them if someone has done this please send pics. I will check the book again to see if I can tell how you are suppost to do this.
Thanks Chris | | |
