July 22, 201610 yr comment_705589 Be interested to hear compression ratios and what valve springs your all running Report
July 22, 201610 yr comment_705590 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 Report
July 22, 201610 yr comment_705592 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 Report
