Thank you for the pictures. I will definitely be having mine checked out. I also need to upgrade the valve springs.

Unless you've done got a plan.. I'd get with Randy to see what he came up with for putting a pipe plug in the core plug hole that's located in the oil drainback area. Aluminum expansion compared to that plug scares me. It being there is what let SM make such reliable/acurate/consistant castings.
A rat tail file, made for aluminum, will get them pushrod holes slotted in no time at all. Quote:

I spoke with SM customer service yesterday (again), got a notification today that order had shipped.
This was for a bare set, and a couple other items. In the conversation the rep mentioned that they were doing things a bit different this year due to the extended back order situation this time last year. All I can suggest is call on Monday.

How often do they offer sales with prices slashed to these "Black Friday" levels?

I ordered a set of these heads online for a flat tappet cam on November 28th and received them December 5th. An older friend of mine who is into Chevies was very impressed how they looked. He also ordered a set of complete Olds heads.

Kept looking for and never got an email notifying me they shipped. Was going to give them until tomorrow, Saturday, then send an email.
Got back from delivering a trailer to a customer, and there on my boss's desk were my heads. Look great. |

One more question: Has anyone checked the springs on the HR version? Is .580" actually the max lift these can (safely) handle? I'm guessing a 1.800" IH?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
