I'm replacing mine this summer with one from Cylinder Heads International, and I'll be sure to announce it happily somewhere in this SPI section of the forum. Gotta show that there's still some running! It's not the most glamourous way to spend money, but it's a necessity. It shouldn't cost too much anyway. The head itself is $225, and I don't think the labour will be much more than $500.
I've learned my lesson from other SPIs on here, that's for sure. It's tempting to spend money on actual modifications (I've allowed myself Eibach springs/shocks), but it would be downright stupid of me to refuse to do anything to remedy a significant problem that I know all about. I like the SPI anyway! Sounds very unique.
Thank god I only have 20K miles on the car.
