Early engine spec question

[zztot]

Doing a build on early 2 liter T engine. Based on upgrades have some piston/valve clearance issues due to bigger valves and DC 30 cams.
From the experts, is there any difference in valve angles ( in essence the heads) in T engine and early S (68/69) heads other than size of valves.
Thanks

Terry, valve angle is the same

Thanks Bruce……We were figuring they should be , but Cam Mfg said something like the valve reliefs in early S pistons were at an odd angle, so needed to check that box before we started trying to fly cut pistons to provide clearance for new cams (DC30s).

Recheck that cam timing

Pretty sure he did several times.
