you put in: Titanium retainers, Double SS valve springs, and new double spring locators

Are you concerned about galling? How are the double springs advantageous?

I'm concerned about galling and cracking which is the reason for the Ti retainers. The double valve springs add considerable resistance to valve float by more aggressively pulling the valve up out of the cylinder when the cam lobe comes off the rocker.

That engine looks pretty clean - how many miles are on it?

It looks like the head is staying on the block. Does that mean you won't be able to clean up the intake and exhaust passeges and do some port-matching when the header arrives? Or can you clean irregularities and flashing with the head on the car?

27,000 miles on the engine, head is staying on block. Last night (pictorial coming soon) we blew any debris (and dead mice) from the intake and exhaust chambers and poured oil into the cylinders to flush out any additional goodies that may have been in there.

Not going to bother with porting/polishing/matching at the moment as I don't know what John (Hytech) has in mind yet as far as runner/collector size for the header and I really wanted to avoid taking the head off.

Alex - suspension suggestion:
I'm in the process of re-designing the suspension in my car and will be using tie rod ends for a R-package Miata. Although I don't know if they will work the same with your relocated rack, these special ends reduce bump-steer in stock NA Miatas. I'll be putting them on my car when I re-do the suspension this summer. This OEM part is available from Mazdaspeed Motorsports.

Hmm, what is the difference?

They correct the angle of the dangle! No really, they change the attachment angle of the inner tie-rod end in relation to the outer tie-rod end on LOWERED Miatas. It basically straightens out the arm and reduces/eliminates the bump-steer created by lowering the car.
