(03-28-2020 01:41 PM)Dave W Wrote: Dan The exhaust side of chambers 4 and 2 (far left, and 2nd from right in photo below) did get some massaging as they did encroach some on the exhaust valves of those 2 chambers. On the intake side, I left it alone as the gap from the valves edge to the chamber wall wasn't that tight, as an example here is a small block Ford chamber (Dart 210cc port performance head) the valve - chamber wall fit is tighter This head also required a thread repair chamber 3, it is a timesert. Timesert is the only real way to fix a spark plug hole. Using a helicoil doesn't transfer the heat properly. A very nice 3 angle valve job.... re-assembly... using Viton rubber valve seals... ... and Sealed Power (VS-813) valve springs - They have a bit more seat pressure, and can accommodate more lift. Dan - You can | .... OR you can ask for help!!! OST Porting service - http://hachiroku.net/forums/showthread.php?t=19991 |
