Thanks for everyones input.

And slantzilla, I wasn't trying to offend you when asking for verification. I had no knowledge of your credentials! Btw, which block are you using. And if you don't mind me asking what type of head work are you running, and fuel/intake?

No problem.

I have a 1970 198 block. There is absolutely no difference between the 198 and 225 blocks except the ci stamp on them.

The one place I spend some money is on the head. I use the late model heads because they do not have the spark plug tubes in them. Mike Jeffrey in Lexington, NE does the work. One head I have is a street head with SB Ford valves and minimal porting. My "race" head has somewhat more work done and has Ferrea valves. Neither head is gasket matched.

Porting is an area where a lot of people get in trouble with a Slant. Bigger is not always better, and can destroy low speed flow just as easily as help.

I also run a lot of camshaft. N/A and nitrous Slants love a lot of lift and duration. It seems the more I throw at it the better it likes it. My current one is an old Clifford that is 300*/.558". My next motor will get more.
