Are thin head gaskets worth the trouble? My engine is assembled and in the car of course, but I know that higher compression will yeild to at least a little more power. What are some other small, useful, easy, and relatively cheap tricks, like that, to do? Thanks

You can't do a much cheaper, greater power yielding modification.

Is that worth 1 hp or 20 hp. I know you cant tell for sure, but its hard for me to know what your saying when you say I will gain power . How much will they change my compression. Thanks

SS67,
I don't know how you can determine the potential HP increase you'd realize, but this thread will give you an idea on the potential compression increase:

There is a couple year old comercially available program called "Desktop Dyno". I saw it at a friends house and have seen it for sale at SUMMIT (www.summitracing.com)under part number MRG-3626. It was fun to play with for a day and it seemed realistic.

I've also downloaded this program and plugged in the specs for the new cars from Road and Track type mags. Its usually within 2 tenths on quarter mile times by the time you figure out gear ratios and all that.

I too like to play with Desktop Dyno (DD). On another bulletin board a guy who was building a new race motor had a contest to see who could guess the actual horespower of his motor when it was finished. I made my guess using DD and got the second place prize money.

It can be pretty accurate depending on how accurate the input information is. The most important item is realistic airflow figures for the head you are using. The generic models they plug in will only get you somewhere close.
