Hey guys i was checking out the CR post above for the 61cc 5.3 heads...i know that is stated for the stock 5.7 but i was wondering if mine will be higher or lower considering i am building a 383 stroker motor with the 7cc cutouts on my diamond pistons...i know you probably want to know what thickness of gaskets im using but i have no clue...ANY IDEAS???? i will more than likely port the heads to add a few more cc's to the heads cause i dont wanna rediculously high CR...any tips would help...i tried searching on here but i couldnt come up with anything...thanks abunch .....

 

using a 62cc head, stock .054 gasket, -.008 deck height, 7cc dish i come up with 11.0 CR

 

cool thanks jrp for the info...
