I was talkin to my local speed shop about ideas in heads and he suggested machining(shaving) the bottom of the heads. the heads I have Now are 1977 74cc and he said he could take them down to 70cc or more to give me a better compression to still run pump gas(canadian pump gas it sucks!!!) as well as saving money rather than buying other heads.
good or bad idea and is it worth it....
Oh. I thought this thread was about skinheads. I'd say go for it. If you don't like it it'll grow back.
Are these heads on the 56 Pontiac engine or a 1977 Chevy engine? If it's a chevy you would gain more power by switching to earlier (pre smog controlled) heads. With a little luck you can find them for less money than milling (or shaving) the heads.
AL
.With all this head shaving going on its hard to tell when yur out in the public if yur in the middle of a Neo-Nazi convention or you just walked into a nursing home.!!......Everybody is looking some damn old.!!!...............Except me of course....:whacked: :whacked: :whacked:
streets is right if they aint warped someone is after some extra christmas money
what would be a good head to run and still get some good performance being non-votec or 305????
Most double hump heads are good, if you can find them, they flow good and are small combustion chambers, How about a thinner head gasket? ever thought of that, steel shim?
Hey Tech.!!..Your the first I've heard tell in a long time of using aluminum paint on shim head gaskets ....I do exactly like ya said ..Bolt em on with a wet coat.....Right on.!!.....:) :)
what is usually worth to have heads magnafluxed???
