Going with that combo on my 89 shortblock from all the digging around I have done looks like it will work out real well. The question is - what rockers to go with? I've read of lots of people running 1.7s but will they give me piston-valve clearance issues or not on the stock pistons with the stock valve reliefs? :confused:
