I'm selling my L36 ZZP Stage 3 heads. Mine I added 130lb spring on both sides and had modified Titianium Retainers. These heads took my car to a 12.02 run last year. I had them on the car for 2 years and just upgraded to ZZP Stage 4 heads. I'm looking for $1,000.00 no core needed on these
quote:
ZZP Stage 3 Heads $1499:
Standard on all ZZP heads:

Factory-hardened exhaust seats left intact. No need for special fuel additives!
Viton valve seals
1.80" installed spring height
Clearanced for lifts up to .650
4 angle intake valve seats
Full radius exhaust valve seats
Optimum port work to intake and extensive port work to exhaust runners, good for .600 lift as shipped (limited by 105# springs). Higher rate springs available by request (double roller timing chain recommended for spring pressures over 110). Heads are resurfaced with less than 5 thousands taken off. Ground finish for better seal with MLS gaskets. No extra charge for milling heads to customer request. We recommend a max of .030 milling and this will increase compression approx .5
