My question is should i deck the block more to get a smaller quench or is the 0.041 okay. The math formulas are driving me nuts but it should give me a compression ratio of around the ball park of 9:3 with the 119cc aluminum heads. they have large intake and exhaust valves. Now the next headache is choosing the right cam were thinking hydraulic or solid roller cam between a 625-675 lift but have idea on the duration yet. i figure it has to be a longer duration because of the longer stroke? another thing is the pushrods for the rocker arms since i decked the block i probably need to resize those, don't i? and how about the distributor? this might be my first and last stroker lol.
throw the copper gaskets out and use a 1017 -1 felpro head gasket there 039 and 10.5 cc and deck to 005 in the hole and call it good .on your push rod they need to be 400 longer as well BUT you need to do a mid lift check for the right push rods with your alum heads they very well could have a hi port more then stock iron by 3/4 so you need to check this there are many things that can throw this off and every engine and with a roller cam like small base circle and decking milling the heads many other things so it needs to be checked. NO if ands or buts you dist can work if you need to know more you can call me my fingers are sore been a long day pat mccarthy 989-667-4071
