-230 cc cathedral ports

CHE steel retainers -used 900 miles, mag checked for cracks
Manley steel valve locks -used 900 miles
New .500x.313 valve seals
New PPI steel spring locators
The heads were used on our race engine and had a rod break. The piston hit the deck and bent the valves on #3 cylinder. The guides and valves have been replaced and chamber welded. There is slight pin holes left over after decking the weld but nothing major. The guides have .0014-.0016 clearance and valve job has been cut on all seats. Total the heads have been decked around .020.
The odd ball items are the following:
-5/16x18 header threads, all others metric
-Dash 3 or #3 fittings at all four corners instead of GM fittings for cross over tube
-springs are set up to have .060-.075 coil bind clearance at .620 lift any more or less will obviously change this as well as open pressure.
I need the money for these for stuff for my house that is why I'm selling. Price does not include shipping. Please text 704-798-7379 or mtopczewski83@gmail.com with questions or offers.

These things will run. Im sure there is plenty of info on flow of these and AFR makes a good head. These will make great power and have tons of deck thickness if you are boosted or NOS.

Yes you should be able to. We ran them originally with Jesel aluminum body roller tips and Jesel bars and a solid roller camshaft. I don't see why a stock bar would have problems bolting on these since AFR sells them without a bar or rockers.
