datzenmike Posted October 19, 2010 Report Share Posted October 19, 2010 Don't know what you mean the valves were knocking into the #1 and #4 cylinders. You mean hitting the sides of the bore or just close to them. The L16 could run a 219 SSS head that had the same valve diameters in it as the A87 so should be good to go. Check the very front of your head ... is there a 219 cast into it???? Quote Link to comment
hooliganPL620 Posted October 19, 2010 Author Report Share Posted October 19, 2010 no 219 casting i have a 219 at my bosses house appears the valves were hitting the bore... left to my own devices aka my mind im thinking the valve guides that were replaced may have had something to do with it when i get my motor back tomm. I will silly puddy the block to head surface and see if its still doing it just me myself and i goin too far thinking next step though is paint the block install freeze plugs crank, bearings run the timing chain and cover and get this puppy together instead of looking at an empty motor stand and wishing so far i still have a hand full of shit Quote Link to comment
