Set of heads that were ported and polished by Ben at WOT-Tech.
The heads were 0 mile casting with factory 3 angle valve seat grind. When they went on my motor they received lapped intake valves and NEW exhaust valves. Factory 3.4 dohc springs, with the largest shim that would fit (I believe .06). Valves did not float at all the way up to the 7k limiter. New valve stem seals.
Heads have less than 2k miles on them. My 3.4 began to leak out the front crank seal and had a bit of blowby due to worn rings - I replaced the whole engine for a stock LX9 motor. That is the reason for selling these heads.
When stock the car dynod at 190 front wheel horsepower on a Mustang Dyno. I never had it dynod with the ported heads but with ported heads, 96 intakes, and 2.5" exhaust it was a considerable improvement. I'd estimate in the range of an additional 50 horsepower above 4000 rpm.
I will post pictures tonight.
$275. You pay shipping, should hopefully fit into a flat rate box.
I paid $180 for the bare 0 mile heads. About $400 for the port work. And then even more for new exhaust valves and spring shims.
