Guys I have a set of clean CJ heads, one clearly dated 8L, the other is the common smudge, I'd say 8J but hard to see, 8 is clear but hard to see letter. They are also on the 428 CJ forum as I figured someone building an early 69 car may want them. Also hung on the old forum.
- Come with a flow sheet (I flow all my heads for cam selection) and spec sheet for installed heights and spring pressure
- Not ported, currently about 255 cfm intake and 187 cfm exhaust at .600, very healthy exhaust port with the SI valves
- Pressure tested when bought, small repair to deck, done long ago, may have been factory repair
- Decks and exhaust face cut
- CC'd at 73.5-74cc
- Bronze guides with Viton seals
- Machined for spring cups
- Tapped for oil restrictors if desired
- Fresh valve job, nice narrow seat
- New 11/32 2.09/1.67 SI undercut stem stainless valves, 45 degree seats, weight savings over factory
- New springs, locks, cups, retainers
- Blueprinted with install heights to 3rd decimal point, and all springs verified for open/close and coil bind on Intercomp tester (well, once spring choice is complete)
Two options for valve springs, can finish with flat tappet traditional springs or if doing a hydraulic roller, PAC Beehives in stock. I generally use 10 degree locks. Can do other options for spring package, but reach out if you have something special. Best to let me know use and cam specs
Can be shipped in about a week depending on spring choice
I just built them for the shelf for a potential future customer build, but all of my scheduled stuff is Trick Flow as far out as I can see, figured I'd throw them out here.
2400.00 plus shipping from Omaha, NE in TFS boxes, not cheap, but all new parts, pressure tested, machined, flowed, blueprinted parts, etc.
