Re: OST-031: A delicate dance
Don't tell anyone, all gasket manufacturers are the only ones to really know the real speed secrets of every head. I hear what I BELIEVE you are saying... I only use OEM gaskets when I work the head, because OEM tends to have more consistancy........ I've gotten a bit further since my last post.......

Re: OST-030: a case in point
If all else remains the same and assuming the bore of the head gasket is 1mm larger than the cylinder bore then you need a volume of 37cc. I should have had you answer these other responses :) Without checking it.. stroke volume is 3.14x41x41x77=369.5 piston sticks up 3.14x41.41.0.3=1.6 gasket is 3...

Re: OST-030: a case in point
Besides the Poncams, my client is using a piston with a 3.2cc dome. He has to check, but believes he has .005" of positive deck - piston slightly ABOVE the blocks surface. He wants to run a squish of .040". What chamber volume does he need for a 11.3 to 1 compression ratio? My clients sai...

Re: OST-030: a case in point
What do you do about bad cam journals and caps? not ignoring you... not quite ready yet to show that part of the process :) Is this a CA customer? 11.3 on 91 octane, better have clean chambers, and management dialed in nicely, my recommendation from experience... I would even worry that improved br...

what's the purpose of that chamfer? any idea why that was machined? for larger valves? It was machned this way because of poor quality control. In my humble opinion - This head should never have been allowed to leave Toyota :!: If you look carefully of the 2 panel showing both sets of chambers, the...
