Solid vs Hydraulic

IMO - if you're considering runnig a hydraulic roller - just skip the expense and run a solid flat tappet. The hydraulic roller is nice but the lifters are heavy, they still wil lcompress and limit ramp speed and rpm, and the pushrod angle really sucks (have the pushrod holes enlarged in any head you use).
If you run a solid roller - which would be my recommendation if the break in still frightens you - then "do it right (again, IMO)" and have the block's lifter bores bushed, keep the cam profile in the "street" zone, and run a high quality set of lifters. A good solid roller, set up properly, will provide a lot of milage without rebuilding or wearing out springs and make a ton of power.
