springersrolla Posted July 22, 2016 Report Posted July 22, 2016 Be interested to hear compression ratios and what valve springs your all running Quote
TOMMYS Ke 11 Posted July 22, 2016 Report Posted July 22, 2016 Have a read of Thomas thread ! I ported the head for him , to get the most out of your port job make sure you put bigger valves in and cam to suit as well as carburation / exhaust and the list goes on ???? . Thomas head has double valve springs at around 105 pound on the seat which once warmed up should be around 95/100 on the seat , compression ratio is just under 12-1 Quote
joshua.mathews Posted July 22, 2016 Author Report Posted July 22, 2016 What larger valves did u use Quote
springersrolla Posted July 22, 2016 Report Posted July 22, 2016 Valve size I can't remember. I bought the head already built and then sunk a heap of more money into it. Will chase emails and measure for you. I remember they were at least 1mm o/s Quote
