Hey Dennis, Hope all is well with you and the new combo is going together. Few questions for ya: On your 198 rod engines, I assume you used an essentially stock head cc (58 or so)? What did your deck height end up at? Should've been around 0.030-0.070" in the hole by my calcs, with no decking. When you ran the MP 0.528" cam, did you need valve notches in the pistons? Any idea on valve-piston clearance you guys measured? I'm finally putting mine together and just thinkin'... Lou |

The last Long Rod 225 I did had a -.020 deck height and I used a small valve notch (.040 deep) mostly for intake valve clearance. DD |

Lou, with no decking on the block I had -.028". No notching required for the .528 Mopar cam. Mike did reverse the pistons on the rods to use the factory notches with the .558 Clifford and 1.6 rockers.  I hope you end up as happy with yours as I have been with mine.

Great to know, guys. I have a motor here from a guy I knew in CA that has the pistons 0.015" OUT of the hole. Might need valve notches. Probably going to run a 0.525" cam I have. Will need a stock cc head and maybe a thick gasket too. Thanks, Lou |

I know Seymour had one with the pistons at +.020" once. He had to do some relieving on the head IIRC. Thanks, Lou
