Selling my 186 heads. These are very nice. 2.02-1.6 SSvalves(under cut intakes) multi-angle valve job. Teflon seals. New springs set up for .600 lift. These heads are dead flat and have been bench flowed and CC'd. For those who do not know. The 186 heads were on the 69-70 high performance SBC's. Like the DZ302..lt-1 and other 350+ factory engines. I have gone 12.5 seconds in the 1/4 mile at well over 100 MPH. These would be perfect for any street or street/strip combo. The chambers are exactly 64CC. The intake runner s are 167CC. Here are the flow numbers and some pics. $500.00 plus ride
