engine is now back from era after porting and ready to rebuilt , i just want to see peoples views on aftermarket water seals , atkins / pineapple or would you just go stock route ? , ported for bw s366 , goopy seals ? stock seals ? and best sources in uk currently , mainly need the water seals as no issues with compression and only 2000 ish miles since it was last built , so side seals etc still in tolerance or would you replace anyway whilst its all stripped down , any help appreciated
