I am going to measure the piston to deck clearance to verify compression ratio this week. When the block was machined and the deck height verified at 10.72", I left the deck height at 10.72. That puts the compression ratio at 12.3-1 with an .039 gasket.
The headers are going to be custom made I was planning on a 2" to 2 1/8" step headers with a 4" collector. I am hoping we can get the tubes all equal length at 32". I am planning to dyno the motor but after the headers are built, I would like to use my headers for the car on the dyno if possible.
I am going to degree the cam hopefully next week so I can check the valve to piston clearance. I have Harland Sharp rockers that are 1.5 ratio right now for the mockup test. Then I can go from there. Lack of parts availability has been a stumbling block so far. Hopefully I will be posting some pictures and status updates in the next couple of weeks. Thanks for the help.
