12 Second N/A Slant 6?

You should go on slantsix.org and look. Doug Dutra....or maybe it was another member.....anyway somebody over there cut a slant head up and they are very thin in that area. It was advised NOT to cut the valve spring seat. But if you decide to, I wish you luck. ...and again keep us posted. I definitely think you're gonna cut a new path with your build.

OK, that's good information,

What did you do to accommodate the longer valve stems on your head? Be specific & post dimensional comparisons for the 318 valve Vs the \6 valves & how much you raised/shifted the rocker shaft. (if you don't mind)

Raising/shifting the rocker shaft might help pushrod clearance for the 1.6 rockers.

I will be taking a LOT from the head deck & quite a bit from the block deck to get my quench distance.

Raising the rocker shaft might bring pushrod angles back into a resonable spec.
