Unfortunately its the H89 that has gone soft. Spewing cause I paid $270 for it as a recently rebuilt head. It looks good!! Valves are all seated properly, nice springs, seals , welsh plug ect. So my next step is to pull the one off the car which is a round port plus I also have another round port on a running engine that is said to have bigger valves and some porting. This motor is down compression on no. 4 cylinder so I am suspecting something is wrong with it ?? Ill just have to have a look at what I,ve got and see what the best option is. Still spewing at the guy who sold me the H89. It's also been decked to 71.86mm. Thanks for all the advice. Will pull them both off saturday arvo n have a look. Thought It would be a simple new gasket H 89 on and go. I am tempted to get the H89 decked and see how it goes?? The didn't even know about soft heads that long ago and it is mainly around the exhaust ports in the middle.
