camatv Posted December 10, 2015 Report Posted December 10, 2015 chariot heads are great, i also dont like how tight they fit. i used a drill bit that just barely fit the hole and kinda reamed them out on the ones i have installed. dont use a drill i just run them through by hand. then they slip down nicely. if your cylindrs studs are tweaked that can be a problem also. unlike some other products. if there is a design flaw chariot has always been quick to fix the issue and make an update. jerry is great to deal with !

Chariot Performance Posted December 11, 2015 Report Posted December 11, 2015 We used a .1mm to small drill on the stud holes a couple years ago and that resulted in a tight fit. We used the correct size the next time though. All good now for sure. Jerry 1 Quote
registered user Posted December 11, 2015 Report Posted December 11, 2015 having the head fit nicely on the cylinder with no movement aint a bad thing. the chamber can then be machined nearly the same as the bore diam. with a bunch of slop like stockers (and maybe some aftermarket heads) the chamber diam has to be a fair bit larger than the bore to account for any slop so you dont get any material protruding into the bore. the down side of this is you create a void behind the piston. this may be the reason chariot tries to keep the holes nearly the same as the studs. just a guess Quote
Chariot Performance Posted December 12, 2015 Report Posted December 12, 2015 We do try to keep it tight for that reason but we had a run that was .004" to tight overall and that made it difficult to fit down easily. thanks Jerry Quote
camatv Posted December 21, 2015 Report Posted December 21, 2015 funny you would mention that. while back i had a stock head and was seeing issues after a bore of possibly hitting the dome. i bolted the head to the cylinder and the hole was WAY off. i ended up machining the dia larger centric to the spark plug hole. what a mess.
