No I haven't. I'll look into cosworth ones. IIRC they are cheaper than the Apex'i ones. Are ARP head studs worth it? This motor probably wont ever see over 300hp.

Right now I haven't purchased a single thing for the motor. That wont start happening till the end of the month. I'm hoping to have the motor assemble by the end of october, then start working on getting the external parts peice together.
