On a stock US 2.0 liter with the dished pistons...
If the head gasket is removed...no cylinder base gasket is installed. What is the new compression ratio...circa??? Do the valves have a chance of hitting the top of the piston... I have not doe this, so I dont know what it looks like yet...just want to see if someone knows already... Rich |

i've seen those valve to piston clearances get to almost nothing on factory cars. ford probe for one using interference engines. no problems as long as the timing belts are good. a non issue for 914's.
just bolt it all up and hand crank it slowly. if it goes round and round you're probably alright. just don't plan redlining it or my opinion becomes null and void. (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) |
