SB Pro Comp Aluminum Heads...For Sale on Ebay..
I forgot about those Tracy. I think Hughes makes them also. So that set up has 4 separate shafts instead of 1. I guess you would not need to use guide plates when using them?
Sorry it took so long to answer Louis. Just couldn't find time before I had to go in for surgery. Yes they have 4 separate shafts per side just like the Hughes rockers so no need for guide plates. I haven't seen Hughes rockers but everyone including top engine builders brag about them so apparently their real good.
The rest of my post is not directed to you Louis. It is to those that commented on the Harland Sharp design.
My post mentioning the HS arms was to merely note that there was an option to using studs to mount the rockers on EQ (magnum style) heads and the pics I posted were to try to show that mounting design for those who haven't seen it, not to say that Harland Sharp's are the only rocker to use and/or the best. I used HS arms because of a few reasons
1. their plenty good for my mild combination that only gets raced 1 or 2 times per year max. With the small cam I used (240 @ .050" and .519 lift solid) and the moderate springs (130 seat, 310 open) I can't imagine having problems with them.
2. their lifetime warranty which nobody else offers.
3. the price was unbeatable at $291 to the door for the complete setup. If they would have been inferior to what I needed it wouldn't have been a good deal, but they aren't, therefore I used them with no regrets.
As a side note, the geometry was spot on.
