I dont know if this is of any advantage to you but i converted to solids to take advantage of a nice head porting job.
A local engineer is doing it and has done it succesfully before. I am providing him with my stufffed hydraulic lifters and he is converting them to solids. I am providing him with the correct springs and rb26 solid cams and he is installing them and setting the lash by trimming the valve stems.
I purchased the cams as near new for 600 dollars, the correct tomei springs cost about the same and the engineer has quoted me 4/5 hundred to do the job. The only additional expense will be the closing of the vct port in the block. Shouldnt be all that much to drill, tap, and put a bung in it.
