Same as the Trickflow's. I didn't know the windsor Sr's came like that. Are you running stock pistons? What kind of lift are you looking at with that cam?

I didn't know much about these heads in general when I got a pretty good buy on them. here is their link

Scorpion rockers are high qaulity, reasonable price and are guarantted for life - they will rebuild them if the bearings start to fail. I've never seen a catastrophic failure of one reported.

Tmoss-
Wada you think I should do. I do not have to worry about coil bind with the 1.7's, if they clear with no piston issues.

Which would you run? My 1.7's are basically new, but money is not a Huge issue right now.
