I'm posting this for my cousin-in-law who is looking for a local sale of these cylinder heads, before they go on Ebay. Let me know if you need more info, and Thanks! for looking.

Dart Platinum 180cc 23 degree aluminum reverse cooled clylinder heads for LT1 applications. These heads are fully assembled, and are approximately 6 months old with 20-25 dragstrip passes and less than 500 street miles on them. These heads feature:

2.02" Intake and 1.60" exhaust valves.

Dual valve springs set up for 130# seat pressure @ 1.800" installed height and .620" max. valve lift. Steel 10 degree retainers, locks, and steel seats.

Intake flows approx. 260 CFM (as polished) at .500" valve lift. As cast flow is 257 CFM, but these heads have been cartridge roll polished. Intake port volume is approx. 182cc (180cc as cast). These heads can be fully ported to yield 285/290+ CFM at .500" lift with approx. 195/205cc intake runners.

Exhaust flows approx. 175 CFM (as polished) at .500" valve lift. As cast flow is 172 CFM. Exhaust port volume is approx. 76cc (75cc as cast).

Complete flow vs valve lift charts will be provided with the purchase of these heads.

These heads have been flat milled .015 to yield a combustion chamber volume of approx. 62cc (as cast volume is 64cc).

With polishing, milling, shipping and tax, he has right around $1,400 in these heads, and will take $1,200 obo for them with local (i.e. metro Detroit) pick up and/or delivery.

Again, Thanks! for looking. PM me here if interested, and I'll pass along your comments, and/or questions.
