ptv clearance? how do i know what heads will give me adequate clearance w/o flycutting? is there a measurement for it or just slap it on and try it out? im trying to get my car to 11.1 or a bit higher compression on a t2 cam and it seems as though ill have to mill to aceice that.
I'd suggest first narrowing down what heads you want/can afford and then looking around to see what people are getting away with in terms of milling, gasket size, valve size, and cam duration. If you plan on getting 243 castings, I can help.

T2 as in Torquer 2?
232/234 ?
Then 243 unmilled Stage 2.5 (2.04/1.57), stock gasket will require the Tv2 on a 113+0.
Those are 64 cc.
Other option is PRC stage 1 (stock valves), stock gasket, unmilled with the 112. Those are also 64 cc
For 11.0:1 you'll have to flycut
232/234 ?
