AJ, that's the point of this thread to remove the "if's and maybes" from my post. The assumptions I made are just assumptions but I stated them as so and backed them up with some logic.
if somebody has done research and the actual measurements before, they can post it up here. Pistons for...
with that much material removed, you should be close to 2degrees off (from my calculations) which does make a difference. Without adjustable cam gears, it is not possible to put them back to stock spec.
it's interesting to hear you haven't noticed any negative side effects and is a good...
oh, Dean Marcum's record setting 13.8 second NA mk3 had a shaved head, to the same compression ratio I am considering aswell. The small details however are unknown.
thanks for mentioning alan's build.
I've read every post but it doesn't really apply to the theory or purpose I discussed. I'm mainly frustrated with the HUGE amounts of misinformation I found when researching this subject.
Hey guys,
I've done a search on this and only found a few, half-assed, non-dedicated threads that don't discuss it thoroughly enough.
I'm doing research for my 7M-GE engine build up, with desire to increase compression in the quest for more power.
from my calculations, decreasing the gasket...

my favourite supra exhaust ever. quiet when cruising and idle but still noticable. does not drone, sounds awesome at WOT. Unfortunatley, brullen has...
THANK YOU JDUB!!!!
I've been looking for that spec everywhere! I've serached "deck height" "head height" "shave allowance" "interference" "head shave" "shave" everything you can imagine and could not find the the measurement anywhere.
hey doward, care to share where you purchased those stainless fasteners?
the local fastenal only wants to sell thngs in large quantities for special order stuff (like stainless metric).
I am considering doing something similar to my motor. I wanted to have everything cadmium plated again, but...
i've read a lot about it being snake oil, I also read a lot about how other people noticed improvements on other forums, so I decided to draw my own conclusions.
last year I did the treatment on my dad's 90 toyota pickup (22-RE). My father is the original owner, it's been maintained very well...
read this, you'll see removing it can be quite detrimental.

However, it will keep your intake a little cleaner, and if emissions aren't an issue it may not be a horrible idea. It's not as critcal on an NA as it is a...
thanks everyone!
Heckler - The valve guides in the supra are quite long, and one of the reasons the valvetrain is quite durable on our heads...they can be cut down, but I'd consider that a race only modification, since it can significantly reduce the life of your seat/valve. I chose to radius...
My roomate uses the nano wax on his black car and likes it a lot. it does look great, but I think I've found two waxes that are even better.
my method is similar to Mike's, but with different products.

- claybar

Alan,
I believe this link will be very helpful. Seamus on CS.com did a comparison of all the headers he could get ahold of. Included in that thread is a link to pictures of every header.
