hey guys i was wondering if you had any recommendations of any reputable shops to have a 99 cylinder head rebuilt and upgraded. i know there’s Corksport but there kind of pricey as well as flying Miata. i was thinking of finding the parts myself and buy them slowly so it wouldn’t be a big amount of money all at once. What parts should i be looking for? i know i would like to get titanium valve retainers, bronze valve guides (any recommendations brand wise?) over sized valves (Supertech the only option?) springs (who makes them?) any other pats im missing?

He did my work for an awesome price, and this guy has a remarkable reputation around DFW and spec miata. He also does a ton of miata engines, and frequenly does 99-head work.

he usually goes through Gary / TDR. He charged me $1100 to service the head without really porting anything, just cleaning up castings, he rebuild the head using the old parts and new wear parts, bored the block, balanced the crank super low, and assembled everything. He's build a few motors which go through hell on the track twice per month. He's a little eccentric too, which is always a good quality in a machinist.

so im a little lost, his headwork cost $1100 or was that price for all that work you mentioned? Including parts?

For the original poster, if you are going to buy some aftermarket retainers and crap for your setup, make sure you arent wasting your money. Like what is the benefit? If its for better rpm control, you would be better off spending your money on springs and leaving the other stuff alone. Im just saying do a good deal of reading up on each modification you plan on doing to make sure it will do what you want it to do and that there isnt something else that could be done cheaper that will do the same thing or better.

$1100 for errything. I don't know what he would charge just for a head job, call the guy. I wouldn't buy anything though, he will get you **** that's been good enough in a number of race cars. He did a bunch of work for big name **** in addition to miatas...including a 900whp sti "texas mile" car.

i work at kehl tech performance in CT, we have a superflow flow bench and all the fixturing to run miata heads, i just made all the fixtures to do my own head(99 head ,race ported,1mm bigger valves,spings retainers,inner shim, the works) we can do just about anything you want except cnc porting. i dont have any prices right now, but if you tell me what your looking to get done i can get you a price, we are very very resonable

thanks guys! i will have to follow up some of these leads next week, as far as parts go what parts are some of you running? is super tech the only aftermarket valves out there? what about good springs?

Where in CT? Be nice to have work done by a place that actually knows how to work on DOHC heads, since my nice, fresh rebuilt head destroyed a cam/bearing surface after a few thousand miles...
