I panicked out of cam confusion. My head is waiting for a spring solution,nothing has been ported yet.I guess i will call OGTS on the 2.2 springs...unless their is a GM option.
Update; my mechanic wants to know ?
1-What is the piston to deck clearance(T.D.C.)?

2-What is exact bore and stroke(my engine is a 20 over 1.9 -9/1(actual 8.4)?

Their plan is to raise my compression to 9.5 to 1 to make this engine something better by decking the block and milling the head.
3- Springs are still a question, their comments were " surely seats can be cut deeper and there are GM springs that will fit to avoid bind with a more aggressssive cam"." "this head looks so GM"
4- are there thinner or steel headgaskets availible?

5- What problem does the rotator on the exhaust spring pose? I got the feeling these can be eliminated.

- the plan is for the car to go " lump-lump at idle...then power at 3,000rpm'

ps: I think I have a weber 38degas for its future.
