i am doing a b20 vtec engine in my da
and was wondering
how or where do you get your block resleeved?
and i was reading this on a b20 vtec engine as i want to build it
"You should avoid advancing the intake cam much as contact will occur between the piston and valves if the cam is advanced much more than 4 degrees. In fact this is so close, it is not really advisable to advance the intake cam at all.
If running larger lift and duration aftermarket cams in your B20/VTEC Frank, or if the head has been modified for higher compression by milling, the piston's valve pockets should be modified and the valve-to-piston clearance confirmed with clay before the head is final assembled to the block. Additional clearance can be obtained by careful grinding the pistons valve reliefs with a die-grinder with carbide burrs and polishing the result with cartridge rolls. A minimum clearance of 0.045" on the intake valves and 0.055 on the exhaust valve is advisable."
can someone explain to me how to do this also as i want aftermarket cams and such?
thanks guys
