Ive just started building a bomb proof 20LET. The LET i used was a late type post 93. So far i have replaced the crank for a knife edged early type 20xe, Flat type flywheel, alloy front pulley, shot peened and polished rods, arp's, copper lead bearings and looking at a oil spray bar(PRICES OF SUPPLY AND FITTING OF ONE PLEASE).
I want to use the early type cam belt as i have heard bad things about the later type. I have all the parts needed to do this but was wondering if anyone else had done this?
Also i have 2 different heads i can use. One early and other late type. Both KS type(dont give me any bull about coscast as there both pressure tested to 40psi in boiling water and the fine!) What i need to know is r the later type bolts any better than the early shorter type?. Also i think the only difference is the heads? am i right or are the threads in the block different as well?
