Just figured it out that after market clutch plates are whack no matter what you do. When tehy heat up they glaze then slip causing shudder. High end TOB don't help. I tried it like I planned above. Will do a clutch upgrade when I install PI heads.
With the T45, I changed to RP. Now it glides, but rear end needs rebuild too. Essentially, short cutting drive train performance on an older car is well, useless. I plan on building from rear to front.

Reference is made to stock clutches. Not high performance, dependable clutch kits.
